Moveset Analysis (Leveling Up):
Ghost-type Lick and Dark-type Bite, Crunch, & Night slash. There is also Normal-type Wrap & Wring Out and Poison-type Poison Tail, Poison Fang, & Poison Jab (STAB). Tactical there is Screech, Glare, Swagger, & Haze.
Moveset Analysis (TM/HM):
Grass-type Giga Drain saps energy away from Ground-types while Bug-type X-Scissor and Dark-type Thief, Payback, & Dark Pulse brings the pain to Psychic-types. Other attacks are Steel-type Iron Tail; Ground-type Earthquake & Dig; Fire-type Flamethrower; Fighting-type Rock Smash; Normal-type Strength; and Poison-type Sludge Bomb (STAB). Tactical there is Sunny Day (helps with Flamethrower), Rain Dance, & Snatch.
Moveset Analysis (Breeding):
Dark-type Assurance makes sure Psychic-types get their just deserts. We also have Normal-type Body Slam & Spit Up (It goes without saying we also have Stockpile and Swallow). Also in tactical there is Scary Face & Switcheroo.
Moveset Analysis (Tutoring):
Water-type Aqua Tail quenches Ground-types while Bug-type Fury Cutter and Dark-type Knock Off & Sucker Punch push around Psychic-types. Other attacks would be Mud-Slap in addition with the usual.

Moveset Analysis (Leveling Up):
ELEMENTAL FANGS! Ice-type Ice Fang specifically frost bites Ground-types with help from Dark-type Bite & Crunch against Psychic-types. We then have Fire-type Fire Fang; Electric-type Thunder Fang; Normal-type Wrap & Spit Up (also got Stockpile and Swallow here too); Ground-type Mud Bomb; & Poison-type Poison Sting, Acid, & Gunk Shot (STAB).

Other attacks are Steel-type Iron Tail; Ground-type Earthquake & Dig; Normal-type Hyper Beam, Giga Impact, & Strength; Rock-type Rock Tomb & Rock Slide; and Poison-type Sludge Bomb & Poison Jab (STAB). Tactical there is Sunny Day, Rain Dance, Safeguard, & Snatch.
Moveset Analysis (Breeding):
Dark-type Beat Up & Pursuit keep chasing after Psychic-types. Normal-type Slam and Poison-type Poison Fang & Poison Tail (STAB). Tactical has Disable, Scary Face, Spite, & Switcheroo.
Moveset Analysis (Tutoring):
Water-type Aqua Tail and Grass-type Seed Bomb erode Ground-types. Other then that it's moves already learned and the usual ones.
Moveset Analysis (Special):
Purify your Shadow Arbok in Pokemon XD: Gale of Darkness to get one knowing Dark-type Bite, Poison-type Sludge Bomb; and the tactical moves Glare and Refresh. And it's refreshing to see a move Arbok can't learn naturally: Refresh.
Arbok will be attacking first but whether its stats are strong enough to take down Seviper before it gets its turn is questionable. If Arbok does an Earthquake then maybe...
MY CHOICE:
ARBOK
(We'll just say it got a critical hit)
Seviper: 1 | Arbok: 3
