Easy, the MTG player actually wants to draw more therefore the +4 benefits him. Neither the gun nor the rooks stand a chance against him at this point.
Have you considered bribery? The drugs may improve performance, but they're addictive, and expensive. That gun could go for a fair amount of money.
Black bribes white to throw the match, and white saves face by pointing out blacks rook count. Player b wins the game, but the international chess committee send them a very, very strongly worded email
its gotta be b bros got 4 rooks on the board he's just missing the sorry piece that white has. the only chance player a has is spending all their lands on a blue eyes white dragon or smth idk i never played poker
It depends on what kind of deck the white player has. If it's cheap hate bears, stax, or board wipes (all the good things in mono white, in other words), then I think they have a solid shot
The winner's spirit is revenant-capable, so the only thing the gun can do is assure a draw. The heart of a champion, while useful in some rites to please the gods is still mortal. So only civil victories are attainable here at least without making an ectoplasmic mess.
