Kindred Boon

The two-mana activation cost is the interesting restriction here: indestructibility is granted not by a keyword the enchantment simply hands out, but by a physical counter you have to pay for, one creature at a time. That converts a blanket-protection effect into an investment problem. Each divinity counter costs at instant speed, so the tribe becomes durable only as fast as you can feed mana into it, and the protection is permanent once placed rather than a one-turn shield. This is the distinction that separates it from board-wide sweeper insurance like Rootborn Defenses or a static anthem: the enchantment does not protect the type, it protects the specific creatures you have already spent on, and the counter stays with the creature even if the enchantment leaves. That persistence is the load-bearing design idea. Kill the enchantment and every divinity counter goes inert, but the counters remain on the board, so a replayed or second copy re-arms the whole crew instantly. It is a slow, mana-hungry engine that rewards a wide tribal board and punishes an opponent who trades removal into indestructible bodies, and it sits comfortably in the lineage of white's "your team can't be killed" effects while asking a real cost for the privilege instead of granting it for free.
