This card is part of a cycle of flip Planeswalkers, reminiscent of those we saw in Magic Origins
Whenever you cast a spell with mana from a treasure, you lose 1 life and draw a card
A deck that combines the ramping magic of Sapphire with Emeralds dastardly trickier, players will also benefit from some pretty insane draw support thanks to the likes of the Floodborn Donald Duck, Sail the Azurite Sea, and Clarabelle, and especially the solid new Cinderella thats making waves in many Sapphire decks right now
With apologies to Mirri, Cat Warrior and Mirri the Cursed, this is the Mirri that I want to equip with a bunch of swords, plates, armors, what have you
For examples Lightning, Security Sergeant needs to remain on the battlefield, Grolnok, the Omnivore can only add croak counters if the card went directly from the library to the graveyard (usually because it was milled), and Kaya the Inexorables emblem only triggers at your upkeep and looks at legendaries
Snuff Out should find a home in basically any deck running swamps
