In my single 2 player game, I got lucky with a pair of cards that came up (the Obsidian triplets one of which I held and another of which I managed to get onto the board with a yellow card) that allowed me to get two cards additional cards in hand in a single turn and more or less instantly assured my victory. I enjoy the game quite a bit and the beautiful materials do their own thing. But the triplets (even just two of them) really frustrated the other player.
