yugioh healing cards Yu-Gi-Oh! - Wave Generator (CSOC-EN001) - Crossroads of Chaos - Unlimited Edition Yugioh Card "Chain Healing" CDIP-KR053

The one extra mana in its cost is insignificant when you consider the extra card advantage

This card is a classic combo with Sanguine Bond and is able to form an infinite loop to drain all of your opponent's life

Cavalcade of Calamity shaves a mana (and half the effectiveness) off Raid Bombardment and supports hyperaggressive go-wide red decks (perhaps even letting players draft Boros aggro)

It's made all the better by having a flying body that gets bigger as you cast bigger spells, leading you to incidental Voltron wins as you plop down small mana rocks to get to huge mana rocks to get to huge Eldrazi titans

These Duelists wear helmets based on the head of "Obelisk the Tormentor"

But any plans that your opponent had are ultimately trashed
