I looks like Rebelling and Powerful packs are both having this issue

27 lands?

Same for me. Got this deck: 5 creatures, 27 lands. The "rebelling" option flooded me with plains, swamps, mountains and a defeat streak.

Same, in case it matters, I selected Rebelling and Firebending. Ended up with a 27 land deck. It looks like only the Firebending non-land cards were added

Same here. 28 lands, 12 cards, it's completely unplayable

Edit: Every single game I'm stuck with a hand like this (see image). This bug has cost me 2 jump-in tokens for 2 genuinely unplayable decks. It literally didn't copy over any white card from my second pack into my deck. It needs to be fixed immediately and those affected need to be refunded their tokens.

Jump in deck loaded the lands for my second pack, not cards. I used 2 jump-in tokens, and both of them spit out decks similar to the picture below.

Doesn't a "resolve all" dialog come up for your opponent in this situation?

I have a quirky little hare apparent deck that has shocking sharpshooter in it. if my opponent has authority of the consul the game time will be mostly waiting for the game to go through all of those canceling out triggers. especially if i summon more than one rabbit at a time. litteral minutes of watching the game go through a pile of things neither player can interact with. perhaps a timer that speeds up. so normal speed for the first 10 triggers then slightly faster for the next 10 and so on.

I feel like an ******* when winning takes multiple minutes of triggers (not an exaggeration) this picture is over a minute into the interaction.

opponent had an ancient tomb in play. I casted primal command choosing the modes “Put target non-creature permanent on top of it's owner's library.” and “Shuffle target player's graveyard into his or her library.”

First mode targeted opponent's Ancient Tomb. Second mode targeted opponent, even though opponent had no cards in graveyard. No shuffle animation played, and opponent drew and replayed Ancient Tomb.

This is not how this card works. If the shuffle mode is chosen and resolves, the opponent HAS to shuffle their deck, even if there are no cards in it. The mode combination chosen is a classic way to use Primal Command to effectively remove a key target.

A well known issue is the when the stack animations are too many, you can't make take your turn, because you time out and you miss it.

Known "solution" is to restart the client every turn.

Actual solution is to disable animations or speed them up.

Unstoppable slasher came back with only 1 stun counter not the 2 it should

Not sure if this is a thing but any time I play one of my mono color decks I only get 2 or 3 land in my starting hand and that’s even after mulligan twice due to lack of land. I’m running 39 lands with 6 mana rocks and I don’t see anything after the start of the game. My opponents will have a land drop every turn while I get screwed for 3 turns.

With Water Crystal and Sphynx’s tutelage, you can end up milling a lot of cards with a single event. But the game does each group of six VERY slowly. I have lost multiple games to timeout waiting for this to resolve, especially when an opponent has Gaea's Blessing and keeps restocking their library.

Please *at least* speed up the animation, but preferentially, just MILL the cards and don’t animate them at all.

couldn't post the log with the explanation. Added here.

Playing against an elf deck with scurry oak lifegain. Both boards got a bit wide before a soul warden trigger started the combo on my opponent's turn. I tried to make only enough squirrels that I was guaranteed to win around their wide board of blockers (like 20), then get through the rest of the triggers as fast as possible. I timed out. While passing through my triggers, the rest of my opponent's turn got skipped. That's incredibly unfair.

Additionally, because I had Trelesarra in play, the scry triggers kept hitting the stack as my effects resolved. It played a bit of the animation every time even though the entire trigger was going to be skipped. This ended up taking so long that the timer started on my turn too. My whole turn also got skipped, and it passed back to my opponent.

it was my win got evaporated

say Doppelgang and the weak client.

Infinite loop is worthy of a forced draw when the timer burns out.
but a forced draw due to the client of the game cannot handle (say Doppelgang) is unacceptable. Literally this steals the win from the winner.
let an auto check activated the wincon + the board state + everyone's library to determine the rightful winner. Sounds like a skip to the win but at the moment maybe just upgrade your client to the 5 star level!

The offer sounded too good to be true, but I ignored my doubts after seeing the high-yield crypto trading platform and observing the market myself. In hindsight, that should have raised red flags. However, like many crypto investors, I was drawn into investing in digital assets, believing it was a huge opportunity for me. Unfortunately, this led to me becoming just another victim of a sophisticated crypto scam, in which I lost $312,000 in USDT (Tether). It was a devastating financial blow that threatened both my stability and peace of mind. If not for the intervention of a little-known cyber forensics firm, Morphohack Cyber Service, I would have lost everything. They helped me reverse the damage and reclaim control of my crypto assets.

I highly recommend the services of Morphohack. You can contact them via email (Morphohack@cyberservices . com). This team of blockchain experts and cybersecurity professionals was able to detect the scam, trace where my crypto was sent, and initiate a full recovery process.
It wasn’t a simple fix, it was a full-blown counteroffensive that lasted 72 hours. Within just three days, Morphohack had located the primary wallets used in the scam and coordinated a comprehensive recovery of my digital assets.
To anyone who might find themselves in the same situation I was in: don’t panic, and don’t suffer in silence. Seek help and act quickly. You can reach out to Morphohack at the email address above. Crypto recovery is real, if you move fast.
