Accelerated Evolution

Flash is the entire pivot here. Green has always paid a premium to keep its threats alive, usually by routing the effect through an instant like Blossoming Defense or Snakeskin Veil that does its work and then leaves the board. Stapling that protection to an aura changes the accounting: cast this in response to a targeted removal spell and the creature dodges the kill spell for the turn while gaining a +2/+2 buff that stays behind after the hexproof expires. That persistence is the trick that a one-shot protection instant cannot replicate, since it collapses a defensive answer and a permanent growth spell into a single card cast at the moment of danger. The cost of that packaging is exposure of a different kind. Once the end-of-turn hexproof lapses, the aura sits on the board as a permanent; enchantment removal peels it off in a clean one-for-one, and the real two-for-one blowout comes from creature removal or a bad block, since the aura dies with whatever it was enchanting. That asymmetry defines how the card wants to be held. Glue it to a creature proactively and you have a vanilla pump aura waiting to be answered; keep it in hand until an opponent commits to a targeted spell and the flash window turns a modest buff into a reactive trap. The design rewards patience, not tempo: its value lives entirely in the moment of interaction, and spending it early throws that value away.
