Turtle Power! - TMC.

Leonardo, the Balance This deck is a five-color, combat-focused strategy helmed by Leonardo, the Balance. The primary game plan revolves around generating tokens to trigger Leonardo's ability, distributing +1/+1 counters across the board, and overwhelming opponents with massive, evasive creatures. The deck leans heavily into a "Mutants, Ninjas, and Turtles" tribal theme, utilizing synergistic pieces to build a formidable board state. Rather than relying on infinite combos, the deck aims for combat inevitability, using cards like Corpsejack Menace and High Score to exponentially grow its threats. Leonardo's WUBRG activated ability serves as a potent finisher, granting the entire team menace, trample, and lifelink to push through lethal damage and swing life totals drastically in your favor.
