Wall =/= Stat up pokemon. both poison jab and gunk shot are good options. The former helps against moltres and pp stalling by steel type (well registeel doesn't really want to switch in but W/E) and has immediate accuracy in the event that arbok doesn't get up enough coils, while the latter has immediate power.
Also, I'd really like to see more realistic spreads; all of these arbok sets should be running 252 HP and 252 SpD IMO; no clue why you guys run speed (to tie with everything in UU.. lol; I think the only thing that is actually harmful to Arbok in that speed tier in UU is.. maybe Blaziken?) or attack (Arbok barely stings anyway with its lolful base 85 attack); its defenses should be 252 HP and 252 Def or SpD on all sets; Arbok is aiming to set up, not to sweep.
