I'm tired of having turn two mountains dropped on my head. The latest was during a historic game where somehow, the opponent mulled down to 3 cards, and played a land first. I used my first turn to thought seize a Trickery from their hand. Next turn they draw Trickery and counter a spell, then somehow land an Ugin and Ulamog on the field at the same time. Totally fair with how little effort and engenuity is needed for this to work. Reminds me of the old days when people tricked out Emrakul turn two in modern with various cards. Only this is worse since it requires only two cards to make it happen. I continue to be surprised by seeing that it hasn't been banned in standard and historic on arena. Wtf?
