mtg murder card Mirko, Obsessive Theorist [Murders at Karlov Manor Commander] Instant Rarity Murder - 134 - CMR

Your opponent would want to remove the Mufasa as soon as possible, but now when they do you get 2 free lore

It's better than Gilded Lotus or similar things that only tap for 1 mana as you can spread the colorless into the various colors as needed

Heliod, Sun-Crowned and Archangel of Thune trigger the same off 1 life or 20

Prioritize cards that have these abilities to keep your opponent guessing your next move throughout the game

Even within the Final Fantasy set alone, several cards come to mind like Zack Fair, Aerith Gainsborough, Rosa, Resolute White Mage, and Auron, Venerated Guardian

That said, Fraying Sanity effectively doubles all your mill against one player at the table
