Radiant Covenant

Whenever a creature you control attacks alone, it gains indestructible until end of turn. At the beginning of your upkeep, if you control no creatures, create a 1/1 white Soldier creature token with Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.) {flavor}“Stand together, shine as one. None shall break our resolve.”
