Algorithm Improvement
I'm sure you're getting a lot of complaints about how one-sided your algorithm is not being impartial and often times screwing over players with land draws that should not be happening in a purely random sample - so my complaint can be added to that pile.
But, an idea for changing the algorithm to improve randomization would be having the program assign a number to each card remaining in a deck and pile shuffling the cards into X amount of piles (let's say 6). It can repeat this process Y amount of times then take the middle of the pile and put those cards on top. A better template would be from the card shuffler for poker sets from stores.

Game rigged 100% certified.
The game keep anoying patterns already identified in other posts.
Tier IV rigged games against antagonist decks calculated by the matching system. More than 1000 games played and recorded whit opponents start more than 750 games (75% of opponent start) it´s out of statistic distribution. Games riggeds giving no lands, no usefull cards or crucial opponets draws in 98% of games. I always play whit top tier tournament decks. The patterns are insane, indeed I can predict the opponent play whit 96% of accuracy!!! Last week when i puchase a boster box climbed to diamon whit no issues. Now with the same decks it´s total impossible. Too much "luck" for the opponent in more than 200 games. No matter the deck you play, rigged matching system takes you out -

beatfux#23804 commented
basically this.
play with g/w ramp --> get all sorts of control or removal decks matched.
play with u/w control --> get all sorts of fast ramp/control decks matched.
they don't even try to hide it.had a conversation over email with wotc support about letting us have technical insight how matchmaking and shuffling algorithms work. got as a reply:
"I assure you that our algorithms, including matchmaking, the shuffler, coin flips, and others, have been tested at length and are working as intended. All players are on the same playing field using the exact same rules."
i answered with some more detailed questions and received a standard "Your feedback about MTG Arena is very valuable to us" blah blah reply. pathetic!this is aggressive ignorance.

even though i beat #93 in mythic....my rewards was moving up 10 positions....its really unfair i hate to be that guy but Wizards of the Coast ....You literally had one job FFS
AND making me play against someone who is 1100 positions infront of me is absolutley unacceptable.
ME Ranked #1250
THEM ranked #93
How does that make sense at all ?!?! easy wins for them i guess i recommend anyone reading this just uninstall the game it is a trap to get you to spend more money and than more money. until you get the deck that YouTube says will win, just to find out you you have to compete with professional gamers. i wont spend another penny on this game. no more season passes. when you are a customer and you are dissatisfied you dont return...so that was i recommend i am done with this BS.

i was mid 800 in mythics yesterday until all the sudden i started getting matched up with people in the top #50 of mythic how is that even remotly fair??? now im in the 1200....im not mad that i lost the games but my decks are decent. it not fair to make me compete with literallty #20 in mythic when i am 850...

Phantus#60520 commented
There is zero reason to have an algorithm meddle in what should be random matches. It really makes the game tedious and predictable in the worst way. Nobody wants to play mirror matches and nobody wants to play hard counters unless they are 1 in 10 due to chance. Please remove it immediately.

Cerahat#50885 commented
It's hard to understand why the matchmaking is rigged. In bo3 ranked I match with nothing but dimir rogues every time. Again and again amd again and again and again this really made me crazy.
I aö not exeggerating. Almost 8 of each 10 games I match with dimir rogues when I play dimir control. If I reconfigure my deck agaimt rogues than I start to match nothing but gruul agggro. This is just top mıch anoing. It really sucks to play mirror matches again anad again. Please fix this ridiculous problem. I understand that by favoring aggro decks you make happy low skill players and this is a good commercial strategy but just know that you **** on this game.

HeadQuarter#85815 commented
The matchmaking in drafts is either trying to make you lose on purpose or seriously flawed. If I proceed to start a draft having Bronze tier, being matched with gold or even platinum tier players shows how something isn't working as it would in a fair, playable, enjoyable gameplay.
Here I report the details of the event, attaching images of the particularly mismatched opponents :
Event : Quick Draft Core 2021 , accessed paying 5000 gold fee on date 2021-01-15
Matches log :
1st match : Bronze opponent, resulting in win, score 1-0
2nd match : Bronze opponent, resulting in win, score 2-0
3rd match : Bronze opponent, resulting in win, score 3-0
4th match : Platinum opponent, resulting in win, score 4-0
5th match : Gold opponent, resulting in loss, score 4-1
6th match : Silver opponent, resulting in win, score 5-1
7th match : Silver opponent, resulting in loss, score 5-2
8th match : Silver opponent, resulting in win, score 6-2
9th match : Silver opponent, resulting in win, score 7-2Since I started the event at the lowest bronze tier, i ended it in bronze tier 1. Therefore, most of the matchmakings here listed were far away from being balanced with my tier.
Please, revise your algorithms.

It would be really nice if WotC would cease with their blatant manipulation of wins and losses via the rigged matchmaking system in RANKED STANDARD, a supposed competitive esports product, as well as cease with the blatant shuffler manipulation which in tandem with the rigging who you match up against is literally deciding wins and losses before a card is drawn in this "strategy" game.
This product is only a fancier version of the three card monte scam.

Antipode82#49495 commented
It's pretty clear from observation that the Arena matchmaker favors specific types of matchups and prevents others.
This makes sense if it were ensuring similar power level decks were paired together, but in practice it leads to a surprisingly high amount of repetitive matches, either mirrors or counter-decks.
To illustrtate this, you can see the odds of being matched against a Gruul Adventures mirror or a Rogues player, of facing a Yorion player while doing BR Midrange, or facing RDW while playing slower decks with higher CMC blue, black or white cards. I've also noticed analogue cases in less competitive archetypes: you have much higher odds of being paired against mono-blue mill while playing UR Spells, for instance. I'm also suspecting this could be due to similar card rarity distributions between decklists, but it's hard to tell without the matchup algorithm or a much larger data set.
I can understand if the spirit behind the matchmaker design is to prevent players with a wide range in power gap from facing each other and having a bad time. However, this is having unintended consequences both in quality of life and deck brewing data gathering.
It's no fun for either player if they get constantly paired against opponents with the same or wildly similar decks, especially if the matchup leans heavily towards one end of the scale or the other, such as Rakdos vs Yorion archetypes, where the BR player has virtually no tools to interact with their opponent's board, or if matches are frequently decided by card sequencing rather than skillful interaction, such as most mirrors between players of similar skill levels.
Moreover, having a matchup frequency bias is probably discouraging deckbuilding experimentation. Players who constantly face their worst matchup in random play will be disinclined to try new options that might improve the overall win rate against a more diverse field. You can see an example of this in the underrepresentation of Underworld Breach in the field, which is an amazing card for BR and UR strategies but a significant liability in their worst matchups.
This also has major implications for seasonal ladder progression: players who rely on random matches to level up will be much more inclined to play decks that have a better overall game against the decks the MATCHMAKER pairs them against, while those who favored matchmaker hard counters will be left behind even though their decks and skills are much higher tier.
I'm not sure what's the best response to this is, and like I said before, I can understand the spirit behind the algorithm, but considering that Arena is one of the few large-community play options for the foreseeable future, I'm worried about the playtesting implications for the community in the long run.

Play mill deck - 9/10 times get matched against either Lurrus or Kroxa deck
Play rogue deck - 9/10 times get matched against rogue deckAtm I'm playing control deck without any outliners (no winning through milling, no rogues in deck) and it's refreshing to be actually matched against different decks. Use any other deck an it's hilarious how repetetive the games become.

Stop spending money on this manipulated and rigged game. The only way that they fix the matchmaking and shuffler shenanigans is if their bottom line becomes affected. Do not buy any product made by WotC or Hasbro, and make this idea known on all social media.
At this point social shaming is the only possible avenue of getting the callous management company to listen to the player base who is apoplectic.

Casserol#09205 commented
I'm sure I'm just another in a long list requesting you tweak your match making program.
I use a third party stat tracker and it's clear as day that your match making leans towards mirrors or at least shared colors/card choices. I have half a dozen decks, play over 30 matches on all of them and the stats don't lie. Mono green will most often be paired against mono green or gruul. Dimir control paired against dimir or esper. It's the same meta. At the time, tournament websites showed gruul aggro as 25% of the meta, yet when playing dimir, they were at the bottom of my played against decks, yet mono green, they were at the top which makes sense, but much higher especially if you consider gruul of the family of green based aggro decks which were well over half my matches with mono green.
I just hope you are trying to change things. I'd like ranked pairings to be based solely on your rank and not deck contents. Just a true rng roll. Casual, I could care less because I can just concede if playing the mirror bugs me that much.
All of my friends have noticed this flawed pairing system, just not everyone has the stats to confirm their suspicions.

Deadskin#95863 commented
Not sure if your looking at why people concede, but OFTEN on a 60 card deck, with 24 lands, I have to concede, because i get 2 lands... multiple mulligans later, it's a concede because you cant make up the lack ofmana.
I find the mulligans system dosent work well online. Maybe a better system is to permit players to convert 1 card to a land card if they are mana screwed...
with 12 mana fetch in my 60 card deck, i can still get mana screwed, something is wrong with this game.
Hearthstone figured it properly, you get 1 mana increment... It's the 1 thing that kills me everytime, either you get just mana or you dont get any, those 2 things are deadly. Dosent involve skill, no play experience, it's pure luck and the mana engin fails miserably in my opinion.
