Should {Belbe's Portal} read "choose creature sub type" instead of "creature type"?
I bring this up because if I played this, could I choose "artifact creature" or would I have to choose the subtype such as "golem" or "sphinx"?
"Artifact Creature" is a card type not a creature type. So you would choose the subtype like you said, ie, Human, Vampire, Golemn, etc.
Thanks, just wanted to make sure that I had been using it correctly
