Infestation Sage
The value proposition here is that the 1/1 body was never the point: it dies, and the flying Insect it leaves behind is the part that survives. That structure makes the card indifferent to being blocked, chumped, or traded away, since the second body is upgraded (evasive) rather than diminished. A one-mana creature that replaces itself with a flier when it dies is a natural fit for sacrifice engines, where the death is the trigger you actually want, and for aristocrat shells that want bodies to feed and drain from without losing tempo. The design leans on the oldest black lesson in the game: a creature that turns its own death into a resource is worth more than its face stats suggest, and the token's flying keyword means the replacement contributes to the board in a way the ground-bound original could not. It is fodder that pays a small dividend on the way out, built for decks that treat their own creatures as consumables rather than assets to protect.
