Vanti, Prophet of Progress

Non-Aetherborn creatures you own that aren't
in play have mutate {2}{u/b}
Other Aetherborn you control get +1/+1
When this creature mutates it becomes a copy of
target creature until end of turn. It is still Vanti,
Prophet of Progress, it is still legendary and
retains all abilites.
"They shall feed our evolution."- Vanti
