Fun Tassa’s Oracle

This is going to be an interesting one to try to break. You need to deal combat damage with an empty library (or mostly empty) and Fblthp in play all at the same time, and he shuffles back in if you don’t win.

I wonder if there’s some way to win with card draw replacement effects? Some way to draw more than two cards from the ability, for example.

I could see WOTC opting to ban Thassa’s Oracle in favor of Fblthp in some formats, though.

Edit: also, with the wording, is it even possible for a player to deal combat damage to another player when it’s not their turn?
