Kronin Key Keymaker

Eminence—As long as "Key" is in the command
zone or on the battlefield, creature spells you cast
have Stealth.
Stealth (This creature has Hexproof until it either attacks, blocks, or use an activated ability.)
Reach, Deathtouch. If Key's Stealth is active he
also has First Strike.
{2}: Give target creature Stealth.
{1}: Taunt—Target player must attack you on
their combat step, and Key must block the
highest power creature.
