This is how good Nintendo is at leakproofing. They've reduced us to discussing counters for a Pokemon that we made up ourselves.
Pokemon Sunday, you can't come soon enough.
Dunsparce doesn't look anything like a cocoon. In fact, I'm not even sure what dunsparce looks like. Some sort of...drilly...thingy.
It's a tsuchinoko! I'd know, I caught one in Metal Gear Solid 3.
The Game.
Castform evolutions (as well as Sandy form added) would be cool. If you level up a Castform while there is Hail, you evolve into the ice form, etc, etc. Give them each their own abilities (Drizzle, Sandstream, Drought, and Snow Warning). Then bump up their stats to 90 each. Drizzle/Drought versions would probably be placed into Ubers, but they would still be fun. The Sandstream evo would be nearly as bulky as Tyranitar on the special side (90 HP, 90 SpD < 100 HP, 100 SpD), but with a much more powerful special STAB. Or they could just add 60 or even 120 points to its BST and make each stat distribution unique. Castform evos seem like a no-brainer given what they have done with Burmy and such.
Adding more move/team slots just seems like a bad idea. I really hope this doesn't happen, as what we have already is enough.
What we have to realize is that something game changing happens every generation
1:Start
2: Introduction of new types and breeding
3: Created Abilities and Natures, as well as the introduction of double battles
4: Physical/Special split
I may not even have everything there, but the pattern still stays the same; something's going to happen.
