Skyreaping

The sweeper as devotion payoff, which is a stranger thing to build than it sounds. Most board wipes price themselves by mana: pay enough, kill everything. This one prices itself by commitment. The damage scales with how many green pips you have already committed to the battlefield, so its ceiling is a function of the very board you spent turns assembling. That ties an anti-flying wrath to a mono-green or heavy-green commitment, the kind of deck whose creatures sit on the ground and whose weakness is exactly the thing being targeted: evasive attackers in the air. The design tension is sharp. Cast it early, before you have built devotion, and it clears a single flyer at best; cast it late, when your green permanents have stacked enough pips to make it lethal to a whole air force, and you have spent a turn doing nothing to the ground threats that a green deck usually has covered anyway. It is a conditional answer that rewards the board state most likely to have produced the problem it solves. Devotion designs of this era kept reaching for ways to convert a color's on-board presence into a discrete effect; this took the riskiest version of that idea, a sweeper whose power you cannot guarantee at the moment you most want it, and pointed it at the one creature category green has always struggled to interact with.
