Ziggs Hex Minefield Question
So there is this combo on ziggs where you pick the schematics Hex Minefield and the one where you can pick which slot should get the damage card. Ziggs can just stay in the back, take damage card after damage card and kill all new minions that have spawned on the rune spaces. So that created the situation that there were no minions altogether. Is there a limit on how often you can play that schematic in a round? If yes is there also a limit on other schematics like Tris Rocket Jump?
