Jack Alltrade

Your maximum hand size is reduced by two.

Whenever you discard your first card each turn,
discard it into exile. If it doesn't have madness, it
gains madness. The madness cost is equal to its
mana cost reduced by {2}.

Delirium — Whenever you cast a card from exile,
if there are four or more card types among cards in
your graveyard, Jack Alltrade deals damage equal to
its mana value to target creature or player.
