Codex of Agony

Catalogue 4 (As this enters the library zone, put the top four cards of a library you own face up on top of this card as a new library. As this becomes empty, put it into its owner's graveyard.)
Whenever you draw a card from another library, if you have three or fewer cards in hand, Codex of Agony deals 1 damage to each opponent for each library you own.
Written in spilled blood.
