Make Blasphemous Act go face for 13WWWBRRR and 13 life
Play [[Tainted Remedy]] and [[Mogg Maniac]]
[[Take Up The Shield]] on Mogg Maniac, giving it indestructible and lifelink
[[Generous Gift]] the indestructible lifelinking Mogg Maniac to your opponent
[[Blasphemous Act]] for 7R, your opponent's indestructible Mog hits you for 13, your opponent loses 13 life from Tainted Remedy off the Mogg's lifelink
[[Eye for an Eye]] the Mogg for another 13 damage to your opponent's face
There's another version of this that's even worse when it hits a board that actually has other creatures on it:
Play Mogg and Take Up the Shield as before. Keep the Mogg
Blasphemous Act as before
[[Blood of the Martyr]], choosing to redirect ALL Blasphemous Act damage from EVERY creature to you, basically doming yourself for 13 times X where X is the number of creatures
[[Gideon's Sacrifice]] your Mogg and dome your opponent instead
