DESCRIPTION
It's a heavy mana cost, but in this deck Invincible Hymn is meant to interact with Cradle of Vitality and Mayael's Aria. When you cast Invincible Hymn, your life total jumps to however many cards you have in your library, then you pay the one colorless and one white to have the amount of health you gained applied to target creature as counters. You would then wait out the opponent's turn, having Mayael's Aria win you the game at the beginning of your next upkeep.
