Gibberjab Wurm

Madness {b}{b}{b} (If you discard this card, discard
it into exile. When you do, cast it for its madness cost
or put it into your graveyard.)
Delirium —Gibberjab Wurm has menace as long
as there are four or more card types among cards
in your graveyard. (A creature with menace can't be blocked except by two or more creatures.)
Never speak to a gibberjab wurm less the gibberjab
wurm speaks first.
