After coming back from a break i decided it was finally time to use my wildcard collection that i had stored to create this red/white equip deck:

2 x Kemba's Outfitter
4 x Fervent Champion
4 x shadowspear
4 x Cloud, Midgar mercenary
4 x Reyav, Master Smith
4 x Buster sword
4 x Sword of Body and Mind
4 x Sword of Fire and Ice
4 x Sword of Forge and Frontier
1 x Astor, Bearer of Blades
1x Danitha, Benalia's Hope
1x Cloud, Planet's Champion
4 x Plains
3x Mountains
1 x Battlefield Forge
4 x Cliffftop Retreat
4 x Needleverge Pathway
4 x Sacred Foundry

(Not optimal, but what i could make with cards i had and Wildcard)

Over the next several weeks this gave me a lot of data. And it is weird and bad.

It all felt really off compared to when i played it with a copy of the deck in IRL.
IRL i would have a lot more streaks where i got too the 3 lands needed for this to operate smooth (yes the deck is on the light side of lands, but IRL it worked smoothly)

Not only did it feel really of compared to IRL, but i noticed i would be matched up with black/white decks about 85% of the times. The first 10 days it did not bother me to much. it is a fast deck and the matches are over quick unless they exile, sacrifice, destroy/discard my creatures. Should they destroy the wrong targets or tap too much of their mana on their own turn to counter the Fervent Champion i could usually sneak a win here and there due too their mistakes or lack of knowledge.

Now, several weeks and many hundred games into trying this deck compared to others when i do the daily quests i can with little to no doubt say that this is rigged in some way. I have no idea if it is the hidden "value" of my combined deck that puts me right into the bracket where there apparently only consists of 85%+ white/black decks, or if their algorithms have gone haywire in another way. But the outcome still remains the same. This has been gnawing on me for quite some time now, but todays matchmaking made me log in here.

Today i have played for 7 hours straight. And i have only met 1 multi color blue/white/black, and the rest have been Black/White decks. (edit: met another blue/white Exile/counterspell deck while writing this)

In the start i thought maybe there were some correlations with the observations and "The Meta", but by changing away from my newly created deck this could easily be proven wrong. With some observation to the cards in the decks fought with my red/white, it got quite clear that it would meet a lot more rare/mythic card decks than if i played a full uncommon historic deck.

I understand you need to protect new players from getting train wrecked by every player that have already played for some time, but the 35 games in a row smashing my head against a Black/white deck before i get 1 match against a the same with a addition of more colors and back into 35 new games against black/white really kills any enjoyment i had for this deck i spent all my collected wildcards too create. It's not like i could even try to fix this situation except throwing a lot of money on it, as there is no "Sword of Light and Shadow" in MTG Arena.

But why would i do that? The decks don't operate as they would in real life, and i don't get put against random people. I have no way to block or Ignore them and I'm stuck in a loop of perplexed bafflement as i just stack more and more evidence to support this claim.

As a long time player of MTG and a vivid draft tournament player, it is really sad to see how boring this issue has made MTG Arena. I've seen friends quit the past month, and truth be told i don't have any argument for why they should not just uninstall. Withe the power creep the recent years they have lost interest in the physical game as well. If anything, this is just another indicator that i should sell my collection before you guys find yet another way to destroy your reputation.

Sincerely, a really disappointed fan.

Two years later...
Soul Sisters (net)decks are still over-represented in Wizbro's NOT-random match making algorithm results. Oh, but if I switch to green - then suddenly it's a green deck...switch back to white or black -surprise, it's SOULS SISTERS AGAIN. The non-RNG is disgustingly blatant.

I think I'm at least a little responsible because I was posting yt vids and winning a lot with lifegain decks
(edit) I played a game where I gained 1000+ life

I have an answer for that. Tainted Remedy! Either digitize it and allow it to be bought with wildcards like many other cards we can't get in booster packs or reprint it in standard with the next set. That'll end life gain decks overnight and make people reliant on that strategy to adjust.

Not sure how exactly to do anything to someone who gains 12 to 24 life for a creature that costs 1 mana. It's inevitable loss and 80% of our games are slogged with these guys.

It’s so boring …especially on events it’s impossible to win even 2games with them ..
I play for fun and study things to improve and get faster my deck .

All time wasted ..u can’t win if u don’t have this 3 deck u mentioned ,thinking to leave the app .too boring ..I could easily replicate one of the elf deck as I have some cards but it get me frustrated

I am sick and tired of playing against the same fracking white lifegain deck, that just spirals out of control!
I don't want to play white lifegain, but apparently its the only way to move foreward. There is such an insane pool of cards that benefit from lifegain, or add to the pile whenever a lifegain trigger, that it's ridiculous.
We have so many cards that says "Whenever you gain life, put a +1/+1 counter on X", and others that just do it to targeted creatures, AND YOU KEEP MAKING MORE OF THEM!
It makes standard **** to go through, since you can't murder everything on the board all the time, and you can't control it. Do something about it, it is ruining the experience for people climbing the ladder... Unless they are the bastards who just netdeck their way to victory.
That aint fun.
Stop enabling it, please.

I didnt know where else to put it, your customer feedback is **** to figure out...

how is it possible , every time i play mono white i am mirror matched , EVERY SINGLE TIME

STANDARD IS SO MUCH FUN WHEN 90% OF THE DECKS ARE THE SAME! I LOVE MONO WHITE! SARCASM IS PRESENT HERE! FOR GOD'S SAKE IT'S BORING AS HECK! AND THEN YOU BRING IN A CARD THAT MAKES REMOVAL EVEN HARDER? WHAT ARE YOU THINKING?
