This was a really cool card that appeared in zexal. I was reminded of it when I saw that Glorious Numbers was getting printed.
Spell - Field
Players can Special Summon a random "Number" monster from their Extra Deck by using 2 monsters with the same Level from their hand as Xyz Materials (This Special Summon is treated as an Xyz Summon. ) If a monster Summoned by this effect has No Xyz Materials, destroy it.
This was a really powerful playmaker in the 3 episodes it appeared. If it were made in real life I would imagine it would have a wording similar to that of Number 78.
Would this be competitively viable? There are quite a few number cards that are good, and a lot of staple ones ( numbers 41 and 39 into S39 come to mind ). I think it would be a pretty neat print
