Description by Fusien:
This team is a cousin of ABR's other Blissey Tealpon Fat, which had a Walking Wake over Samurott. The presence of Blissey + Pech + Skarm create a strong blanket defensive answer to many offensive attacks, and pressure is exerted through Gliscor + Tealpon + Samurott. Terad Tealpon gets a +1 speedboost upon entry, acting as the speed control of the team when needed.  This team has several variations it can undergo. The primary one is that of the Gliscor: a set consisting of Toxic + Earthquake + U-Turn + Protect, with Tera Fairy and an ev spread of 244 hp/ 56 def/208 spdef Impish nature allows for a more effective Gliscor for some matchups, but the lack of immediate breaking heightens the risk of opposing Calm Mind Clefable. SD Glisc does better against this threat, and aids far better in breaking fat cores, at the risk of struggling a bit more against other metagame threats due to not being able to Toxic. A more mixed Defensive Gliscor than the current one can be tried potentially to help with Gambit/Oger (Impish rather than current Careful). Samurott can be Jolly if one wants to gaurantee an outspeed on non-scarf Timid Gholdengo, and on the last move, Encore can also be Flip Turn/Sucker Punch. Encore, however, allows for greater deterrence against SD Gambit/Ceruledge. Tera Water is to have the option for a stronger Razor Shell against Gliscor. Blissey Tera depends on what threat one wishes to be better against: Poison covers AV Body Press Kyurem and Nasty Plot Pecharunt while being weaker to Hex Darts Pult, Tera Fairy misses out on NP Pech while covering the other 2, and Tera Steel Misses out on AV Press Kyu. Skarm can be 96 Speed evs to become faster than speedy Adamant Gambit, but this cuts into bulk. An alternative is to make Blissey Rocks over Toss, and make Skarmory an Iron Defense + Body Press + Brave Bird Corviknight, making Gambit mu better, but this comes at the risk of running a more constrained Blissey set, and of losing the option for Whirlwind. A whirlwind + iron defense skarm could be hypothesized instead, but whether this could be effective hasn't been tested. Lastly, Pecharunt is toxic to avoid Malignant Chain's 50% chance to not-poison normally, and its failure to poison against Covert Cloak mons, neither of which Toxic fails against.
