Dragon's Den

Whenever you loose life, a creature you control
dies, or you sacrifice a non creature permanent
that isnt a Treasure token, create a Treasure token.
{1}, sacrifice a Treasure token: create a 2/2
Mercenary creature token that's also your choice
of a Rogue with First-Strike, Wizard with Reach,
Barbarian with Menace, Knight with Vigilance,
or Druid with Lifelink, and is the color of your
choice.
{2}, sacrifice two Treasure tokens: Amass 4.
