Echoing Truth, the blue instant in the cycle of Echoing cards, returns a permanent, and all the other permanents in play with the same name, to their owners' hands. What is the most powerful use of Echoing Truth you could imagine?
What about returning two enormous Affinity creatures after all the artifacts in play have been removed? Like, say, using it on a pair of Furnace Dragons?
