2. Characters whose main cards are in a box will most likely never come. Boxes are profit bait.
Especially if they have many cards and most or all of them are in a box, which not only make the box a bigger profit bait for those who love the deck, it also result in the characters having practically no relevant cards left to give via drop and level up.
- Viper (all the Venom cards are in the box)
- Rafael (all his Guardians are in multiple different boxes, both main & mini)
- Sherly (I'm baffled by this, to be honest)
- Misty (only has 1 Reptilliane left for DL)
And while we're on this topic, no, we're not getting Valon either. His deck needs 5 zones to properly work. We only have 3.
It really just depends on the popularity of the character and if they can find a purpose for them. That being said, I don't see a character like Valon or Misty happening. They're not popular enough, and they don't really have a good enough gimmick for a skill or the like to make them work. Though it's worth pointing out that Misty probably does technically have enough of a cardpool to work with.
There’s two reptilianne, Naga & Lamia left plus they can add generic EB immortal support or reptile support with her. Adding her wouldn’t make the most exciting event but they can just use her to fill in the support cards for the immortals while the other sale signed get their respective archetypes.
