Since Tuvasa is your commander, you only need to get it to 21 damage on each opponent before you win, something incredibly easy to achieve while you protect it with an Asceticism and beef it up with Ethereal Armor and All That Glitters
One way to do so is by benefiting more from the forced sacrifice triggers
Decks that people already dread to sit across from like Tergrid, God of Fright and Tinybones, Trinket Thief will love this card
Aliases are accepted: prereqs , step , cycle , disrupt , outcome , win , in-play / board / field (= battlefield ), in-hand / cards / pieces (= hand ), variant / variants (= line ), inf / infinity (= infinite ), etc
These cards serve valuable utility in Dimir reanimator decks in Legacy, which use blues unmatched stack interaction with blacks hand disruption and Reanimate, which is trivial to set up with pieces like Entomb or Troll of Khazad-dm, or even targeting yourself with Thoughtseize
