Does it really matter how it works? It looks monstrous. Besides, if your opponent was running Nexus+++, Gravity Mage+++, portal +++ and Summoner+ you prettymuch win the game without even doing much to begin with.

Kidding aside, I have no idea which ability target it would port things to. Default answer is the normal one for the moveset it took the squares from but clearly that might not be the whole story.
