Duty Beyond Death

The sacrifice is not a cost the card apologizes for: it is the fulcrum the whole effect turns on. Team-wide indestructible answers a board wipe or a blocked alpha strike, but pairing it with a global +1/+1 counter turns a defensive reflex into a permanent upgrade, so the same instant that saves the team also grows it. Feeding one creature to the spell to make the rest bigger and unkillable is the kind of trade a go-wide board almost never minds making, and the fodder often carries a death trigger you wanted to cash anyway. The timing is the sharp part. At instant speed, this waits until the opponent has committed: it lets a Wrath of God resolve into no dead creatures, and it wins the combats that would otherwise be losses, whether you are the aggressor pushing an attack into open mana or the defender declaring blocks. Cast before combat damage, your creatures survive the exchange and come out the far side one counter larger than they went in. Indestructible does nothing against exile, bounce, or -X/-X, so it is a specific answer rather than a blanket one, and the sacrifice clause means you cannot cast it on an empty board to bluff. What it represents is the white combat trick evolving past the single-creature pump: a one-card payoff that rewards a wide, counter-hungry board for the price of the least valuable body on it.
