Proten, God of Amalgamation

Indestructible
If your devotion to blue and green is less than 7,
Proten isn't a creature, and has no other abilities.
{u}{u}{g}{g}, sacrifice a creature: target creature
perpetually gains all abilities of the sacrificed creature, and becomes an Amalgam in addition
to its other types. The sacrificed creature is
exiled.
Through sacrifice, disparate powers intertwine,
forming a tapestry of unparalleled beauty.
