Maybe, but with cord, if he is not being used in his own world, he goes down in one turn, no exceptions. Cord also can only attack once, def is so low that even size 0 can defeat him, and penetrate is meaningless against open center decks. Normally these problems can be remedied if he has dragoarms, especailly with the new dragoarms, but in other worlds, it is just dead weight.

Grangadez, on the other hand, can be usuable on other worlds. Sure, he needs 4 gauge to call, but the cost is worth it. He has to be destroyed/removed from the field 4 times, has double attack so he has options of how to attack, and has move to support open center decks. Sure, Grangadez is not that good of an omni lord, but he makes a solid wall and field clearer.
