Id be all over this if it were a Gruul commander, but as a mono-red, it falls just shy of exciting me
Much like with Tainted Aether, you cant just jam this card into your Yarok deck and go to town, but if youve got a way to win the game or deal with the Carnival once it starts to kill youwell, the ability is quite powerful
Not being an instant is far more significant on this spell as it can't deal with man lands and, while still very versatile, feels more over-costed than vindicate and is thus a very clunky card
Sidenote - I love how everyone tried to play "Mulligan Mewtwo" using 4 of this and 56 psychic energy and Barrier their way to a win when a single Energy Removal card destroyed the strategy
The best one, though, is that for five additional mana you can destroy all creatures
Sephiroth, Fabled SOLDIER / Sephiroth, One-Winged Angel Sephiroth, Fabled SOLDIER is a fantastic little sacrifice commander
