Id love to have the infamous Sorrows Path here, but Ive previously talked about it in an even more fitting list, so its time for Raging River to get the spotlight
Either way, combat ensues and you, the Boros player gain the advantage
Ulamog, The Defiler just barely beat out Emrakul, the World Anew by about $50
In a one-on-one game, this card is practically a death sentence for the other player, taking out their whole board and stocking your hand full to bursting with new options even if you dont finish them off on the same turn
It's not the ideal board wipe in a deck full of mana rocks, but the opportunity cost on it is so low, and it's better to sweep the board than to die (unless the game has already gone on for like an hour)
This asks way too much of you for a 7-mana card
