Overview Another generation and another round in UU for Blastoise. Back in BW2 UU Blastoise was first, foremost and only a Rapid Spinner. Unfortunately with the rise of Defog and the fact that hazard stacking simply isn't as popular as it used to be mean pure Rapid Spinners are not in high demand. Fortunately though, Blastoise was one of the few Pokémon gifted with a Mega Evolution, meaning for the first time in ages it can do more than just Rapid Spin. That said, it is still a brilliant Rapid Spinner, arguably the best in UU - that Mega Launcher boosted Dark Pulse keeps the Spinblockers away. Mega Blastoise is your textbook bulky attacker - with 79/120/115 defences, it's tough to bring down without super effective hits and with that brutal 135 base special attack it can do a lot of damage. Mega Launcher helps it in this role, giving it several attacks with over 100 BP (factoring in STAB for its Water moves). The shellfish does have a few problems however. That great bulk is undermined by no recovery at all besides Rest, since it can't hold Leftovers. Even with that 135 base special attack it finds itself struggling to fend off special walls like Florges, and it takes up your team's Mega slot. And if you decide to fallback on regular Blastoise's old Rapid Spin set, it will often find itself set up fodder due to its lack of power. Offensive Rapid Spin Blastoise @ Blatoisinite Modest Nature (+SAtk -Atk) Trait: Torrent EV: 252 HP / 4 Def / 252 SAtk Water Pulse/ Scald / Hydro Pump Dark Pulse Aura Sphere/ Ice Beam Rapid Spin This set is Mega Blastoise: a bulky Water type that packs a fair punch, and can also Rapid Spin. Thanks to Mega Launcher, Water Pulse is essentially Surf with more PP and a chance to confuse the opponent. That said, Scald's 30% chance to burn the opponent is not to be overlooked, although it is a bit weaker. Hydro Pump is even more powerful, although the sub par accuracy and low PP make it far less reliable. Dark Pulse hits for 120 power thanks to Mega Launcher, and allows it to slay the Pokémon most other bulky Water types fear: Jellicent. Aura Sphere also hits for 120 power thanks to Mega Launcher, and gets wonderful coverage with Blastoises's STAB and Dark Pulse. However, Ice Beam is a fine alternative in that slot to badly hurt UU's Grass types on the switch. Rapid Spin is used in the last slot: Stealth Rock is still common, and with the fear of that Mega Launcher boosted Dark Pulse UU's Ghost types will not fancy switching in. The EVs maximise Blastoises's power and overall bulk, enabling it to give and take a fair bit of punishment. You could invest 180 Speed EVs to outrun 0 Speed base 100s, but generally the extra bulk is more helpful. Defensive Rapid Spin Blastoise @ Leftovers Trait: Torrent Bold Nature (+Def -Atk) EV: 252 HP / 252 Def / 4 SAtk Rapid Spin Foresight Scald Roar / Yawn / Toxic If you've picked another mega evolution, and for whatever reason Forretress, Starmie and Donphan don't float your boat, Blastoise can always fall back on its old Rapid Spin set. Rapid Spin is self explanatory. Foresight enables Blastoise to spin against the Ghost types attempting to spin block. Scald gets STAB, and that handy burn chance could spell doom for an incoming physical attacker. The last slot is dedicated to making sure Blastoise doesn't become set up fodder. Roar works instantly, although Yawn could give one of your teammates a chance to set up. Toxic can cripple incoming Jellicent and Gastrodon. The EVs maximise Blastoise's physical bulk. A physically defensive spread is superior to a specially defensive one, since most of the Grass and Electric moves you see in UU are special attacks. Other Options Dragon Pulse gets a Mega Launcher boost and OHKOs Haxorus, but Ice Beam gets better coverage overall. You could reconfigure Mega Blastoise's set to be a great Baton Pass recipient: simply move the HP EVs into Speed, use a Timid nature and either Ice Beam or Dragon Pulse in the 4th slot. At +2 Speed it outruns Scarfed 108 Speed Pokémon, and can 2HKO pretty much anything. You could EV regular Blastoise to be more specially defensive, but since its 2 weaknesses are 2 types which are generally specially based (at least in UU) a physically defensive spread works better. Checks and Counters Toxicroak is immune to Water moves and resists both Dark Pulse and Aura Sphere - it can then set up in Mega Blastoises's face and take it down with a boosted Gunk Shot or Drain Punch. If it lacks Ice Beam, bulky Grass types like Roserade, Syamin and Whimsicott can beat Mega Blastoise without too much trouble. Faster Grass and Electric types can usually beat Mega Blastoise one on one, although they might have trouble switching in. Thundurus-T always OHKOs with a Life Orb boosted Thunderbolt, and can avoid a OHKO from Ice Beam most of the time if Stealth Rock isn't down. Mega Manectric outruns and 2HKOs with Thunderbolt, but can't switch in since Water Pulse 2HKOs. Mega Amphoros can shrug off most attacks bar Ice Beam, and OHKO most of the time with Thunderbolt. Regular Blastoise is pretty easy to counter due to the lack of offensive presence. Gastrodon and Jellicent wall it completely, but both will hate Toxic. Celebi, Roserade and Shaymin can all switch in on anything it does and smash it with their super effective Grass STABs. Toxicroak is immune to Scald and Toxic, and can set up in its face. Reuniclus can smash Blastoise with nothing to fear bar Yawn thanks to Magic Guard. If they can avoid a burn, Salamence and Haxorus can all set up in Blastoise's face, taking little from Scald, and take it down with boosted Outrages. Most offensive Pokémon unhindered by or immune to burns can deal with Blastoise easily enough.
