Delirium — Whenever this creature attacks while there are four or more card types among cards in your graveyard, it gets +2/+0 and gains menace until end of turn. (It can't be blocked except by two or more creatures.)

Haste When this creature dies, exile the top card of your library. You may play it until the end of your next turn.

({T}: Add {R}.)

As an additional cost to cast this spell, sacrifice an artifact. Create three 1/1 red Goblin creature tokens.
