Alanya, Mechanical Messiah

Flying, First Strike, Vigilance, Indestructible
Whenever a spell or an ability an opponent controls
targets a creature or artifact you control, you may
have that spell or ability target Alanya instead.
At the beginning of your endstep, you may put a
+1/+1-counter on each other creature you control.
Those creatures are artifact creatures in addition
to their other types.
