Don't Try This at Home - Unfinity - 105

Enchantment

Mana Cost: {1}{R}

If a hot source you control would deal damage to a permanent or player, it deals that much damage plus 1 instead. (Something is hot if it has hot things in its art, like fire or explosions.)
{1}{R}, Sacrifice this enchantment: It deals damage equal to twice the number of hot cards in your graveyard to target creature or planeswalker.
