Dark Tulpa

When Dark Tulpa enters the battlefield is a
duplicate of target creature under your control.
(Dark Tulp gains same title, types, abilities,
power and toughness as target.)
{t}: Add {b} to your mana pool.
It has been speculated by some scholars of the arcane
that the phenomena of Dark Tulpas is related to psionics
and might arise out of the unconscious frustration of
repeated failures to use their powers effectively.
