Sigarda, Heron's Grace

Where the earlier Sigarda, Host of Herons kept your permanents off the sacrifice block, stopping opponents from making you feed edicts and annihilator triggers, this version reroutes the protection into targeting: hexproof for you and every Human you control. The clause reads wider than it plays. It covers your Humans, not your whole board, so the effect is meaningful only when the board is Humans in the first place, and that constraint is the entire design. A tribe of one-toughness Human tokens is normally the softest thing green-white can commit to the table, exposed to every point of spot removal. Under this umbrella those same fragile bodies become untargetable, walking past Doom Blade effects that have to name a creature. The hexproof Sigarda grants you does separate work: because targeted "you sacrifice a creature" effects choose the player, a hexproof controller cannot be made their target, so the classic single-target edict misses you entirely. The graveyard activation closes the loop, spending dead cards to manufacture more Humans and refill the very board it shields. The seam between the two halves is where the power lives: protection reaches only Humans, the token engine builds only Humans, so committing hard to the type is the cost of the whole package rather than a splash. As a five-mana 4/5 flier she is serviceable on her own; as the anchor of a Human go-wide plan she pushes opponents off targeted answers entirely, onto sweepers and combat math, the two things she cannot legislate away.
