Not only does it have deathtouch and first strike for guaranteed victories in combat, if Master of Cruelties deals damage to an opponent, that players life total also becomes 1
It leans harder into the ping theme, and it makes use of some established Pauper artifact powerhouses
Shes an Angel, so you could certainly start with multicolored, mostly Boros, with green as a small support color for Sigarda, Host of Herons, and of course some ramp spells

Best for: Players who primarily build decks and want basic "do I own this" tracking on the side
