Ogre Savant

The conditional clause is the entire design: the bounce fires only if blue mana paid into the casting cost. Because that requirement lives inside the generic four-mana portion rather than as a separate kicker payment, a mono-red deck casts a plain 3/2 whose triggered ability never fires, while a deck splashing blue routes a through that generic cost and gets a creature stapled to an Unsummon. This is guild gold-card structure without the gold frame: the body reads pure red, but the rider is gated behind a second color that red sits opposite on the pie, rewarding a manabase built to support both enemy halves rather than a token splash. The trick belongs to a family of designs where a creature reads as one color yet unlocks an extra effect when an off-color mana contributes to the cost, and this version folds unusually cleanly into a recursion loop. A 3/2 that returns a creature once is filler; a 3/2 that re-enters and bounces a creature again each cycle becomes a tempo engine, with the spent-mana condition as the governor. You never get the trigger for free: every loop demands the full five mana with blue routed through it. The payoff is a clean bounce welded to a beater, available only to a player willing to commit to the second color rather than wave at it.
