This thread deader than my soul in JC. Like most of my life, reviving it is probably a mistake.
Blastoise @ Icium Z
Ability: Torrent
EVs: 252 HP / 252 Def / 4 Spe
Bold Nature
IVs: 0 Atk
- Scald
- Blizzard
- Rapid Spin

0 SpA Blastoise Subzero Slammer (185 BP) vs. 0 HP / 0 SpD Sceptile: 266-314 (94.6 - 111.7%) -- 68.8% chance to OHKO
Not a good lure, but it does lure Sceptile in. Guarantees a KO after Rocks but you lose a slot for Toxic/Refresh.
Slowking @ Assault Vest
Ability: Regenerator
EVs: 212 HP / 252 SpA / 44 Spe
Modest Nature
IVs: 0 Atk
- Scald

252+ SpA Slowking Fire Blast vs. 0 HP / 0 SpD Sceptile: 252-298 (89.6 - 106%) -- 37.5% chance to OHKO
252 SpA Life Orb Sceptile Leaf Storm vs. 212 HP / 0 SpD Assault Vest Slowking: 291-346 (75.7 - 90.1%) -- guaranteed 2HKO
For if you're feeling ballsy enough to stay in.
Seismitoad @ Poisonium Z / Life Orb
Ability: Swift Swim
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Rain Dance

252+ SpA Life Orb Seismitoad Sludge Wave vs. 0 HP / 0 SpD Sceptile: 255-302 (90.7 - 107.4%) -- 43.8% chance to OHKO
Toad is either weak or Sceptile is deceptively bulky. Adamant Max Attack Life Orb Poison Jab OHKOs though.
Vaporeon @ Icium Z
Ability: Water Absorb
EVs: 252 HP / 252 Def / 4 SpA
Bold Nature
IVs: 0 Atk
- Scald
- Ice Beam
- Wish
- Protect
0 SpA Vaporeon Subzero Slammer (175 BP) vs. 0 HP / 0 SpD Sceptile: 312-368 (111 - 130.9%) -- guaranteed OHKO
0 SpA Vaporeon Ice Beam vs. 0 HP / 0 SpD Sceptile: 160-190 (56.9 - 67.6%) -- guaranteed 2HKO
Beats other Grass types that think they can wall you as well (like all the above sets).
Palossand @ Colbur Berry
Ability: Water Compaction
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
IVs: 0 Atk
- Stealth Rock

- Sludge Bomb
- Shore Up
0 SpA Palossand Sludge Bomb vs. 0 HP / 0 SpD Sceptile: 148-176 (52.6 - 62.6%) -- guaranteed 2HKO
Finally not a Water type. Has the added benefit of being able to poison.
Sceptile isn't coming in on anything that isn't a bulky water/ground so apologies for the uncreative sets.
