Galaxy-Eyes Photon Dragon
You can Tribute 2 monsters with 2000 or more ATK to Special Summon this card from your hand. When this card battles an opponent's monster, during the Battle Step: You can banish that monster and this card. Return the banished monsters to the field when the Battle Phase ends. If the monster banished by this effect was an Xyz Monster: This card gains 500 ATK for each Xyz Material that monster had attached to it when it was banished.
A Blue-Eyes White Dragon for the Zexal era, this card is great for leaving your opponent's Xyz Monsters without effects, but that's all it does. It gains a bit of attack, but this card really doesn't do anything else. You can summon it by tributing 2 monsters, or Special Summon it by tributing 2 monsters with 2000 or more ATK, so either way, you lose out on card advantage. The only other use I see is to get rid of your opponent's Stardust Dragon or Legendary Shi En so you can play a card they would normally negate. Unless someone proves me wrong, I refuse to believe this card and the whole Photon archtype is good.
Number 10: Illumiknight
3 Level 4 monsters
Once per turn: You can detach 1 Xyz Material from this card; send 1 card from your hand to the Graveyard and draw 1 card.
With 2400 ATK, you'd probably be better off sticking with the three Xyz Material Monsters you would use to summon this. If it weren't for the three LV4 monster requirement, this card might have seen some play in Exodia/OTK decks. The best you could hope for is to send a card like Dandylion to the Graveyard and plus off its effect. I still see Steelswarm Roach as the only good Xyz monster so far. Prove me wrong, people.
Since Pot of Duality is in wave 1, I'm going to venture a guess that Solemn Warning will be in wave 2, and unless Fossil Dyna Pachycephalo is in LC2, it'll probably be in one of these as well.
