Cascade is a wild ability, but when you can reliably make it happen it gets even wilder
It is five-mana and sorcery speed, which isnt great, but the upside of getting a copy of whatever you removed is worth it
(To manifest a card, put it onto the battlefield face down as a 2/2 creature Turn it face up any time for its mana cost if it's a creature card.) Other colorless creatures you control get +3/+2
I have no words other than that this card is very, very powerful

The combination of double strike to help finish the game and card advantage to grind through longer ones makes this a potent Boros card for token decks, though you cant use it much elsewhere
