Eloise, Augmented Death

Mech-Augment {2}{c}{c}
Whenever a creature you control dies, put a
charge counter onto Eloise, Augmented Death.
Then if Eloise has ten charge counters on her and
is augmented, remove six charge counters and
conjure a Legendary Construct Artifact creature
named Agrellion, Tyrant Reborn onto the battlefield.
