I am trying to play simic in standard, and play around interactions with Doubling Season and ways to duplicate it such as Doppelgang and Oko planeswalker -5, and you would think this is the perfect kind of deck to play online virtually, since we are creating a silly amount of tokens a lot of the time, you would think. However deeply disappointing at the climax of this deck's potential, when large amounts of triggers are on the stack and are being duplicated by doubling season such as Overlord of the Hauntwoods and Spelunking giving about 500 untapped mana, or doppelganging an opponent's urabrask's forge, or other large interactions the game will stand still, appear as if you lost connection and result in a draw.
I don't know if your servers are capable of housing such a deck, and to me this is the most fun I've had in the game when it works, and I've put in a decent amount of money to craft the decklist I'm playing, you would think there would be no issues. So I don't know what to do other than try to bring this to your attention.
