Eidolon Teralyst

Adaptability (Whenever this card receives damage,
it can no longer receive damage from that source or
from a source with the same name as long as it is on
the battlefield.)
Other nonlegendary sentient creatures you
control get +1/+1.
If Eidolon Teralyst is put into a graveyard from anywhere, shuffle it into its owner's library. If it
was destroyed, return it to its owner's hand.
