On support tentacruel, I would mention substitute in AC as an option over t-spikes and toxic. I have used it with much success in the past. That way you can burn stall things to death a lot easier than if you used the sub-toxic set because you have protect in the moveset. It might seem like it makes it an inferior sub-toxic tentacruel, but its not, its simply an option over toxic or t-spikes to provide a different kind of support. I think its a solid AC option, at worst OO.
also blizzard probably needs mention in OO for use on hail teams
