Faerie Impostor

The bounce cost is the entire transaction here: a one-mana 2/1 flier sits well above the curve for a body, and the entry clause makes you pay for the discount by picking up another creature you control. What reads as a tax becomes an engine the moment the returned creature has its own enters-the-battlefield trigger worth replaying. Pick up something that drains, scries, or makes a token on arrival, recast it, and this Faerie has functionally untapped that effect for the price of one evasive blue body. The sacrifice clause is the discipline behind the rate: skip the bounce and the Faerie dies on the spot, so you never get the flier for free unless you have a target lined up. That requirement doubles as a timing wrinkle, since the return fires on entry and not at will. You cannot hold the Impostor open as an instant-speed escape hatch for a creature about to die; the reset only triggers when you commit this body to the board. It is a small, deliberate cog in a blink-and-replay shell, inert among vanilla creatures and a genuine accelerant in a deck stacked with arrival triggers.
