Thanks to the converge mechanic, it rewards multicolor decks by letting you tutor up a creature, instant, or sorcery with mana value equal to the number of colors you used to cast it
Id also argue it is an actual release, though
Heat Breath costs two Energy to start using and has a base damage of 30
When a Special Summoned monster activates its effect while you have a "Shaddoll" card in your hand (Quick Effect): You can negate the activation, and if you do, destroy that monster, then send 1 "Shaddoll" card from your hand to the GY
It invalidates any meaningful artifact or creature its opponents play, which makes it a wildly powerful control tool that also wins the game thanks to a steady stream of 3/3s
