Maybe Masked Dragon? It would be great to make Armed Dragon more competitive, and it could substitute the Labyrinth Builder skill together with Bastion's Hydragon.
There's also Light and Darkness dragon. Maybe more Ojama or XYZ union support.
I'm expecting Voltanis (or maybe Herald), considering Superb Tea's theme. Some easy to use counter trap like Drastic Drop Off/Dark Bribe/Negate Attack would be nice too.
Note that Tea and Chazz are all getting a SINGLE new card each. (The news post is pretty clear about this.) My guess would be Voltanis or Power Angel Valkyria for Tea and Genesis Dragon (maybe a slim chance of Armed Dragon Catapult Cannon, but unlikely) for Chazz.
instead of fairies I'd like to get some of the magician girl cards from Tea that Yugi played in Dark Side of Dimensions like Lemon Magician Girl. Magician's Valkyria would also be great.
If we still don't get Sanctum yet, then honestly I'm fine with either one of these:
- Voltanis the Adjudicator
- Power Angel Valkyria
- Minerva, Scholar of the Sky
