I was in a game when the opponent had a card that created 3 times as many tokens as creatures were attacking, then i had a card that gave them all -1/-1 so it destroyed the ones attacking(about almost 100) and then it needed to create almost 200 more then he healed for each one that came out...the timer was going the whole time all this was trying to resolve almost forcing me to concede because I couldn't take my defending action because it had to wait for it all to resolve luckily i got the time like just seconds before the concede timer ran out to win the game with mill. This timer going off while cards are resolving needs to be fixed it definitely interrupts that game-play and is not the players fault the game cannot resolve such things in an instant type manner.
