Glacial Dragonhunt

Draw a card, then you may discard a card. When you discard a nonland card this way, Glacial Dragonhunt deals 3 damage to target creature.

Harmonize {4}{U}{R} (You may cast this card from your graveyard for its harmonize cost. You may tap a creature you control to reduce that cost by {X}, where X is its power. Then exile this spell.)
