Battle Mastery
Double strike on an Aura is the cleanest way to print the keyword and the most dangerous to attach to anything fragile. The math is brutal: any creature wearing this hits for twice its power, turning a two-power attacker into a four-damage threat and a real evasive body into a clock that ends games in two swings. What pays for that ceiling is the Aura chassis itself. You spend a card and three mana to upgrade a creature already on the battlefield, and a single removal spell in response answers both the Aura and the body underneath it at once: the two-for-one that has kept this kind of combat-keyword Aura honest since the earliest examples. The reward structure points the card at one place: a creature with a damage rider worth multiplying. Trample, deathtouch, lifelink, an on-damage trigger, anything that scales with combat damage dealt rather than damage threatened gets doubled along with the numbers, and that is where the card stops being a fragile pump spell and becomes a finisher. The gamble runs in one direction: stack your offense onto a single enchanted attacker, expose both halves to one answer, and bet the game on the turn it connects.
