Big Deck games take 10 minutes to start
With a maximum allowable 1400 cards per deck, 2 decks of this size will cause a 10-minute wait between game "start" and actual die roll. Also applies to reloading battlefield after sideboarding, so possible 30 minutes of waiting in a 3-game match. Though 1400 cards is the extreme, it was never a problem before the Ikoria release. Even two 700 card decks cause a 6-7 minute wait, and two 250 card Prismatic decks ("minimum big deck") can take over two minutes to roll the die and load the battlefield. Again, was never an issue prior to Ikoria release. What changed in the game engine?
