Tifa's Limit Break

One green mana holds three spells, and the tier you pay for is a decision made at the moment of casting rather than baked into deckbuilding. Somersault costs nothing extra and hands over a flat +2/+2, the humble early-combat mode that keeps this from ever being a dead card. Meteor Strikes doubles power and toughness for two more, and Final Heaven triples both for a genuinely steep eight total ( up front, on top). Because the two upper tiers multiply rather than add, they scale off whatever creature you aim them at: a small body climbs slowly, a haymaker rockets. That is the structural payoff of stapling all three effects to a single slot: a pilot never holds a redundant pump spell, because the same card is a cheap trick when the board is small and a finisher when it is large. What limits the ceiling is that the expensive tiers only earn their mana when there is already a threat worth multiplying; aim Final Heaven at a 2/2 and you have paid eight to make a 6/6, aim it at a 6/6 and you have made an 18/18 at instant speed. The scaling clause turns a plain green trick into a decision problem, and the decision is always about the creature, never the spell.
