as title. I let the autotapper cast vibrance for me. my lands in play are: steam vents, starting town x2, secluded courtyard and cavern of souls(both naming elemental), breeding pool x2, island. instead of tapping in a sane way, autotapper tapped starting town for a colored mana pip while I was at 1 life and just killed me instead. my best guess is it wanted to keep UU up for deceit in hand, but uh, it should probably not tap to lose you the game.
