Agares, King of Manticores

Shadow, First Strike

This creature has +1/+1 for every other black creature you control.
At the beginning of your upkeep, discard a card from the top of your library; you may then draw twice.

When this creature is destroyed, you may instead exile it and shuffle your graveyard into your library.

Though he was the smallest and frailest of the Chimera, not one dark creature question him...
