Gryff's Boon

Auras have always carried a structural tax: you spend a whole card to make one creature better, and the first removal spell to answer that creature erases both at once. The graveyard recursion clause is the answer to that bargain. Pay one mana up front to grant evasion and a little reach; when the enchanted creature dies (or the aura itself gets picked off), the buff does not follow it into oblivion. Three mana and white at sorcery speed buys it back onto a fresh body, converting a fragile one-shot into a repeatable evasion engine that a defending player has to keep killing creatures to suppress. The +1/+0 is incidental; flying is the point, and the recursion is what makes paying for flight again and again worth doing. This is the same instinct that keeps Rancor a perennial pickup: an enchantment that refuses to stay in the graveyard rewrites the math on every removal spell aimed at whatever is wearing it. The cost is the discipline. Bringing it back is deliberately slow and color-locked, so the loop grinds rather than free-reattaches, and the body it lands on still has to do the attacking. What the recursion clause really sells is inevitability in the air: one swing at a time, no matter how many attackers the opponent trades away, the flight keeps coming back.
