Oh, that monkey looks funny. I really hope Acrobat has at least 50 base power, though. (So that it becomes at least 100 when without an item). The monkey'd still need some support to get into Gluttony range, though. I mean, we cannot hope for it to NOT be OHKO'd by CB-Outrage. (Especially since I still expect Garchomp back in OU. No "strategy" has ever remained broken for more than 1 generation.)
However, regarding the entry hazards: I also expect GF to balance SR, obviously. And while we do not expect that big changes in the game mechanics, I expect one or many of the following things to happen:
- We get a good Rapid Spin. There could be different degrees of "good", though: The most basic case would be a Rapid Spin clone of a different type (Psychic would make sense and also have an offensive immunity). If GF is even nicer, we get an unresisted Rapid Spin. This could be as simple as finally giving the move to Miltank. And to totally fuck up entry hazards, we could have a really good move with a "spinning" side effect. I think it'd make sense if Earthquake removed grounded spikes (although we already have enough EQ in OU) and Stone Edge broke Stealth Rocks.
- We get an auto-spinning ability. If it worked like Intimidate it'd be at least weak to double-switching. It would kinda guarantee that its best user is instant OU, though. Way to fight over-centralizing...
- Stealth Rocks (and possibly also Spikes, although Toxic Spikes would need to change their mechanic a bit) affect both sides of the field. It's a simple change that would still allow certain teams to be based around entry hazards, but much in the way Sandstorm is used now.
Also, I consider some of these "debuffs" to be so strong that they could very well be combined with even more entry hazards (kinda the way someone suggested the "ring of fire"). And I must say I suspect something like that, because from what we know, every Generation has introduced some ADDITION to entry hazards.
