Combos Utilizing Recoup

duh...

toast 24 cards from a library with just these cards

cast that expensive sorcery out of your graveyard for less mana. the more stones in play, the cheaper the cost.

animate a land, eradicate it use recoup on eradicate and do it to another type of land

this only works if you have a whole lot of mana, but if you use searing flesh, then radiate it, you'll take seven damage in the process, but they take fourteen. then use recoup to do it again to kill
