You’re right, the game shouldn’t be too complicate, but I think, the “if” cards are more complicate than "continuous" cards.
I don’t think, that newcomers will be overextended, because the main principle is easy, it would be invitingly to pick these cards in his/her deck for all ranks of MArcomage players, its easy and on a high level.
But it’s your game and I don’t want to be importunate.
