OCG Test [Dimension Union - Heroes on the Move]

[Kingdom Xathers]

I wanna be sure that the OCG for this is, at the very least, fluent, before I post the actual card for my Set ([b]the part in question will be bolded[/b]):




Dimesion Union - Heroes On the Move

Spell/Normal

Special Summon, from your hand, Deck or Graveyard, 1 each of "Ratchet - DH", "Jak and Daxter - DH" and "Sly Cooper - DH". [b]If you already control a monster(s) with the above names; You cannot Special Summon a copy of that monster(s).[/b] Monsters Special Summoned by this effect cannot be used as Xyz Materials.




Of course, feel free to comment on the effect itself. But really, i just need help with the OCG more than anything.
