Adaptive Automaton
{3}
Artifact Creature -- Construct
2/2
As Adaptive Automaton enters the battlefield, choose a creature type.
Adaptive Automaton is the chosen type in addition to its other types.
Other creatures you control of the chosen type get +1/+1.

* The choice of creature type is made as Adaptive Automaton enters the battlefield. Players can't respond to this choice. The bonus starts applying immediately.

* You must choose an existing _Magic_ creature type.

* Even though Adaptive Automaton is a Construct, other Construct creatures you control won't get +1/+1 (unless you chose Construct as Adaptive Automaton entered the battlefield).
