*Good base 120 Special Defense, but base 80 Hp and 65 Defense pulls it back. *Fast base 100 Speed, considering Tentacruel is primarily a special wall. *Mediocre base 70/80 dual Attacking stats. *Recovery in Rain Dish *Unique Water/Poison typing is good for a defensive pokemon on Tentacruel. *One of the best spinners in the tier == Support == Tentacruel (M) @ Black Sludge Trait: Rain Dish EVs: 252 HP / 236 Def / 20 Spd Bold Nature (+Def, -Atk) - Rapid Spin - Toxic / Toxic Spikes - Scald - Protect / Substitute / Sludge Bomb Set Comments: *This set excels at spinning away hazards for both balanced and stall teams alike. Unlike other users of Rapid Spin, Tentacruel is able to absorb Toxic Spikes, facilitating its work as a spinner. Tentacruel isn't limited to spinning either—it can spread status and stall out many threats. *Although Tentacruel has access to Toxic Spikes, Toxic is still the preferable move. This is because many teams benefit more from the immediate poison, and there are also many Flying-types and Levitate Pokemon that can only be poisoned by Toxic. Toxic also has other advantages, such as allowing Tentacruel to consistently defeat most relevant spinblockers in rain. Nevertheless, Toxic Spikes is still a viable option, and Tentacruel has a niche as one of the few viable users of this move. Toxic Spikes is preferred on stall teams, or when using a sweeper that benefits from certain walls being crippled, particularly those with Natural Cure. *The third slot goes to Scald, the best STAB move that Tentacruel can run. It has the same power under rain as a Hydro Pump outside of rain and has a 30% chance to burn the target, discouraging Pokemon such as Gyarados and Dragonite from switching in, even though they resist the move. The move in the fourth slot depends on your preference. Protect is the main choice, as it allows Tentacruel to stall for more Leftovers + Rain Dish recovery. *Protect also has the ability to scout Choice users and stop SubDisable Gengar from ruining your day. Another good option is Substitute, which blocks status and Leech Seed, and most stall teams typically have trouble breaking Tentacruel's Substitutes. When using Substitute, remember to only use it with Toxic, and not Toxic Spikes. Sludge Bomb is a good choice as a secondary STAB move to put the hurt on Breloom and Celebi. Ice Beam is also a good idea to freeze the flying dragons that love to use Tentacruel as set-up bait. *Rain Support is obviously needed so that Tentacruel can recover health using its ability and help prolong Tentacruel's lifespan on the battlefield. *Liquid Ooze can also be used to damage leech seed users and moves that drain away Tentacruel's health, punishing them by reducing their health instead of gaining health that it has absorbed. == Offensive == Tentacruel (M) @ Life Orb Trait: Rain Dish EVs: 4 HP / 252 SAtk / 252 Spd Timid Nature (+Spd, -Atk) - Hydro Pump / Surf - Ice Beam - Sludge Bomb - Giga Drain Set Comments: *Starmie generally outclasses this set due to its higher Speed and Special Attack, access to reliable recovery, and a superior offensive movepool. The surprise value and unique typing gives it a small degree of viability, though. *Hydro Pump under rain is going to put the hurt on most pokemon. Surf can also be used if you are afraid of missing Hydro Pumps, but the power will be missed *Ice Beam deals with the flying dragons that simply love switching into Tentacruel, and punish them for the naive thought that Tentacruel is set-up bait. *Sludge Bomb serves as Tentacruel's secondary STAB, bringing down Grass-types such as Celebi and Breloom. *Giga Drain hits its water-type bethren for SE damage, while recovering Tentacruel's health. *Due to this set lacking greatly in power, Entry Hazard support is greatly appreciated to dish out more damage. == Other Options == *Tentacruel can run a funny SD set, as water and poison STABs have surprisingly good coverage. *Knock Off is an interesting utility move, especially considering that it can make Leftovers users succumb quickly to poison. However, Tentacruel has trouble finding room to accommodate this move. Confuse Ray deals even more damage to the opponent if you are lucky, but Tentacruel has more consistent options to run. *Magic Coat can block Taunt and status moves, but on Tentacruel, this move is rather gimmicky. Acid Spray could be used to force out opponents in fear of taking attacks at -2 Special Defense, but Tentacruel still isn't very threatening offensively. == Checks and Counters == *If Tentacruel is running Toxic Spikes, anything that is immune to them and doesn't take much damage from Scald can be considered a counter. Reuniclus, Latias, Latios, and Hydreigon are prime examples. The former two even have super effective STAB moves to use against Tentacruel. Dragonite and Gyarados actually fit the above description, but they will hate being burned, unless they run Substitute or Lum Berry. *Poison Heal Breloom is one of the best counters to Tentacruel, as it benefits from being poisoned and can use Tentacruel as setup fodder. However, be wary that Breloom is vulnerable to Scald burns if it doesn't have its Toxic Orb activated and Toxic Spikes aren't on the field. *Celebi is probably the best counter to Tentacruel, as it can simply cure itself of status when switching out, takes little damage from most of Tentacruel's attacks, and can easily dispose of it with Psychic. *Amoonguss absorbs Toxic Spikes and takes almost no damage from Scald, but it cannot retaliate aside from using Spore. Venusaur can also remove Toxic Spikes, set up Growth, and mitigate potential damage from Ice Beam or Scald burns with Giga Drain. *Toxicroak is completely immune to everything in Tentacruel's arsenal and can remove Toxic Spikes. Even though Tentacruel resists both of Toxicroak's STABs, it may be overpowered after a few boosts. *SubCM Latias and SubCM Keldeo aren't bothered by anything that Tentacruel can throw at them and can set up on it easily if they haven't been poisoned by Toxic Spikes or by Toxic on the switch-in. *Both Alakazam and Reuniclus do not have to worry about status at all, and can easily dispose of Tentacruel with their STAB moves, although Alakazam takes decent damage from Scald due to its natural frailty. *Starmie can spin away Toxic Spikes and can force Tentacruel out with the threat of STAB Psyshock, Thunderbolt, or Thunderbolt. Natural Cure means that Starmie does not have to worry about status. *If Tentacruel lacks Toxic or has not set up Toxic Spikes, Jellicent has no problem coming in to block Rapid Spin and can beat it one-on-one with Taunt, Will-O-Wisp, and Recover. I should stop spamming the OU analyses, shouldn't I?
