Silver Drake

A 3/3 flyer for three mana is a clean rate, but the mandatory return clause is what defines the card. The bounce reads broadly (any white or blue creature you control), so the design is really asking what you point it at. Aim it at itself and the Drake comes back to hand, ready to be recast, at the cost of a tempo stall: you replay the same body next turn whenever there is nothing better worth resetting. Aim it at a creature with a worthwhile enters-the-battlefield trigger and the line flips: the body becomes the delivery mechanism for resetting a value engine, and the flyer keeps swinging while you rebuild. That tension is the whole design. It belongs to the long tradition of self-bouncing white-blue flyers, where the bounce is sold as a cost on the front of the card and quietly functions as a tool on the back, depending on the board you build around it. The flying matters more than the keyword suggests: it keeps the body relevant as a clock even on the turns when there is nothing good to return, so the card never collapses into dead weight. What it asks of a deck is a reason for the trigger to exist, not just a creature to hold it.
