Axel, The Storm Emperor

Hexproof, Lifelink
Tap Axel, The Storm Emperor: draw a card,
then discard a card at random. If you discard
a nonland, noncreature card this way, it deals
damage to any target equal to its converted mana
cost and you gain that much life. Activate this
ability only at the beginning of your upkeep.
