I tested a lot of these sets when I was looking for ways to use Blastoise, and most of them (all of them) are pretty bad. Not to mention that they're pretty much outclassed completely to a point that they're unusable. Water Spout is not a good move on Blastoise considering it's Special Attack sucks. If Burungeru can't do it, sure as hell Blastoise can't considering that Burungeru actually has instant recovery. I would
only keep the first set, which is the closest to usable, although Blastoise can
NOT stall. It can only Rapid Spin. If you want to stall, use a different Pokemon. Red is delete. Blue is add. Blastoise's speed isn't good enough for an offensive Rapid Spin set. That is better left to Starmie (and possibly) Tentacruel.
[SET]
name:
Stall Tortoise Rapid Spin
move 1: Rapid Spin
/ Rest (Rest with the new Sleep Mechanics is a no-no)
move 2:
Substitute / Ice Beam / Protect (Protect isn't for stalling - its for getting leftovers/Rain Dish recovery-It can also help wrack up Toxic Damage or work with Yawn if you are using those)
move 3:
Toxic / Dragon Tail / Roar Dragon Tail / Yawn / Toxic (Dragon Tail on Blastoise is pitifully weak; it can't even break Gengar's substitutes. However it still is able to phaze Spinblockers) (Yawn is a good alternative to Dragon Tail for phazing) (Toxic is also usable since it cripples Spinblocker switchins that lack Status recovery)
move 4: Boil Over
nature: Bold/Calm
ability: Rain Dish
item: Leftovers
EVs: 252 HP / 56 Def / 200 SpD
(Due to Blastoise's pure water typing and high Defense, it works better when it is physically defensive - it helps differentiate itself from the likes of Tentacruel in that it actually stands a chance against things that pack Earthquake. It serves as a good last-minute check to Doryuuzu since it isn't OHKOed by +2 Earthquake or 2HKOed by +0 Earthquake (non Life Orb). I would leave the Specially defensive spread in Additional Comments)
And the Final Product:
[SET]
name:
Rapid Spin
move 1: Rapid Spin
move 2:
Dragon Tail / Yawn / Toxic
move 3:
Boil Over
move 4: Ice Beam / Protect
nature: Bold
ability: Rain Dish
item: Leftovers
EVs: 252 HP / 252 Def / 4 SpD
Pretty much a full revamp.
Edit:
Water Spout at full health has a huge Base Power of 337
No it doesn't.
It's only 150 Base Power.
225 with STAB.
