Galan, Scavenger Looter

Whenever you gain life you may draw a card and then discard a card. If you do, Galan deals damage to any target equal to the coverted mana cost of the discarded card.
Whenever you discard a land card you gain 1 life and create a colorless Treasure artifact token with "{t}, sacrifice this token: add one mana of any color to your mana pool.".
