GreError with triggers from Cultivator Colossus
Game end in Draw because of GreError when I use 'Cultivator Colossus' ability with a lot of lands. Having 'Druid Class' in game make the problem worse. Each single action begin to take more than 15 seconds as the client 'lag' a lot within this state. When a stack of at least 20 triggers happen (which really doesnt sound like abusing the game, we're not on hundreds of triggers), I'm pretty sure the game will GreError each time.
