Psychic Pickpocket

Connive was the mechanic that let blue-black split the difference between filtering and looting, and this is what happens when you bolt a bounce clause to the front end of it. The enters-the-battlefield connive does two jobs at once: it smooths your hand toward what you want to keep, and if you pitch a nonland it grows the body from a 3/2 into a 4/3 that can pressure a race. But the return clause is what gives the card its texture. "Up to one target nonland permanent" is deliberately wide: it can pick off an opposing blocker for a turn, reset a token or artifact off the board, or (the aristocrat move) rebuy one of your own enters-the-battlefield triggers to run again. Because the whole package fires only on entry, and the creature has no flash, none of that flexibility comes with the instant-speed leverage a flash creature would offer: you commit the body and take the tempo swing on your own turn, when your opponent can see it coming. The word "nonland" is the other leash; without it, this would be Man-o'-War stapled to a land-bounce loop, and five mana is the price paid to keep the swing honest rather than oppressive. This descends from the blue tempo creatures that turn a body into a two-for-one, but where Man-o'-War only ever bounced a creature, this one reaches noncreature permanents and pays you card selection on the way in.
