Tiger Claws

The interesting thing here is the flash, not the stat boost. Most permanent auras of this era resolved at sorcery speed, which made them a known liability: tap out for an aura, get blown out by an instant-speed removal spell, and you have lost two cards to one. Flash rewrites that exchange. An attacker who walked into a profitable block can suddenly trample over for more, or an unblocked creature can grow at the last beat of the combat step before damage. The trample is what makes the surprise math nasty: an opponent who chumps to absorb a creature finds the body too large to contain, and the leftover points spill through. The +1/+1 alone is modest; pairing it with trample and instant-speed deployment turns a vanilla pump into a combat ambush that punishes the defender for committing blockers early. The cost of that flexibility is the permanence problem most auras carry: it is still a two-for-one risk if the enchanted creature dies, and casting it in advance forfeits the very element of surprise that justifies the build. The card's whole identity lives in the gap between when you could cast it and when you should, holding it until the block is declared and the opponent has already made the decision they cannot take back.
