Hello my dear friend,
Recently I’d built up a deck that generate lot of tokens using Zendilar’s Roil and Part the Waterveil, when the effects goes to stack, take a long, long, very long time to generate all the tokens. Same with Kiora Ult, that generate 4 Octopus.
My suggestion is reduce the show card/flash animation after the first token. Just blink the lens/flare effect.
For futures releases of game, please setup a config mode, that we can enable or disable graphics animations. Just for the game to be flatter
