mtg from the vault relics card list Set From the Vault: Relics

Whenever you cast a spell that targets a creature you don't control, Legolas deals damage equal to its power to up to one target creature

The key difference here is that Banner of Kinship only enters with counters if you already have the creatures in play, so its more akin to an Overrun

If Thancred Waters leaves the battlefield or you lose control of it before its triggered ability resolves, the target legendary permanent won't gain indestructible at all

I scoured all the emblems and could not find a single relevant death trigger

These cards looked extremely rough: yellow cardstock, photocopied text, handwritten notes, and simple doodles instead of finished art

It works well in myr decks since youll have a lot of creatures to tap along with the four tokens it creates
