@thewhitedragon69 I'd actually be very interested in data with a % of matches that would have been won by the opponent on their next turn, as I feel there are also a good % of blowout matches.
That should be fairly easy to gather data on, if anyone feels like taking notes on their next playtesting or tournament
Annihilator 1 (Whenever this creature attacks, defending player sacrifices a permanent.)
Triggers at the declare attackers step, so won't work.
This card would really need haste, and you need a big creature in your hand to work. I'm guessing it could work in Survival. You can always get Emrakul when needed, and discard it when not.
