Sigarda, Host of Herons
Hexproof on a creature protects it from being targeted; the third line of text protects your permanents from opponent-forced sacrifice. Edicts, sacrifice clauses, the entire school of "you don't get to choose what dies" removal that exists precisely to route around protection and shroud: none of it touches a board you control while this Angel is in play. That combination is the design point. A five-mana 5/5 flier that opponents can't target is already a clock that conventional removal struggles to answer; bolting on a global sacrifice immunity closes the back door that edict effects were built to be. The result is a creature that defends itself with one keyword and defends the rest of your permanents with the static line below it, which is a rarer job than the body suggests. Most hexproof threats are selfish; they keep themselves alive and leave the rest of your board exposed. This one extends its umbrella outward, neutralizing a removal axis for an entire side of the table rather than for a single creature. The cost of all that resilience is that it does nothing proactive: no evasion math beyond flight, no card advantage, no reach into the graveyard. It is pure obstruction, a wall against the specific answers that ignore the usual ones, and it asks the opponent to find the narrow slice of removal that goes around both targeting and sacrifice at once.
