Consolidated PBY Catalina

Crew 7, Flying.
{t}: Create a 1/4 transport ship artifact creature
token with haste, decayed, and "When this
creature deals combat damage to a player, you
gain 3 life." Consolidated PBY Catalina then
escorts it. (Until end of turn, a creature blocking
the escorted creature must fight the escorting creature first.) Activate only if Consolidated PBY Catalina is a creature.
An effective convoy escort, the "Cat" could fly for over
24 hours.
