Themon, Embodiment Flame

At the beginning of your upkeep if Themon is
on the battlefield, discard your hand, then draw cards equal to the number of cards
discarded this way.
Whenever you discard a card, if it is an instant or sorcery it gains madness until end of turn, its madness cost is equal to its converted mana cost.
You may cast Themon from your graveyard.
