Shapers' Sanctuary

Removal-protection in green usually wears a different hat: a hexproof or shroud body, a fight spell, a regeneration shield. This takes the opposite stance. It does not stop the kill spell or the bounce or the tempo swing; it lets them resolve and hands you a card while it happens. Every targeted answer an opponent aims at your creatures (a Lightning Bolt, a "destroy target creature," a bounce spell buying time) becomes a one-for-one that also refills your hand, so the trade that would normally cost you a threat leaves you even and them down a resource in the long game. The one-mana cost is doing real work here, because the payoff is entirely reactive: it draws nothing on its own, generates no advantage until an opponent decides your creatures are worth interacting with, and rewards a board wide enough that the opponent cannot simply ignore your threats. Note that it triggers only on interaction pointed at your creatures, so edicts (which target the player) and an opponent's own pump spells never wake it up. That dependency is the balancing line: it feeds the deck that floods the board with must-answer threats, then converts each answer into fuel. A taxing card disguised as a protective one, and a clean expression of green's recurring idea that the right response to being interacted with is not to dodge the interaction but to outpace it.
