In defense of Lickylicky, I've used it quite effectively in UU- if you can remove your opponent's fighting types, lickylicky can run a set of rest/talk/curse/dragon tail (wish illegal with dragon tail). This allows it to tank quite effectively- for instance, I run 252 hp/252 spdef/4 att, and after a curse or two i can take hitmontop close combats reasonably well (uninvested, I'm guessing, but still).
However, looking over your team, I'm very tempted to drop the balanced part and go for pure stall. If you were to do this, it would mean some major overhauls, but I think it could be effective. If you were to do this I'd suggest:
Shaymin --> Roserade
252 HP / 120 Def / 136 SpD Calm
-Leech Seed (Over sleep powder due to the amount of status on your team; helps wear down walls and provide extra recovery).
Spikes + sleep/seeds. Restswitch for natural cure.
P2/Lickylicky --> Umbreon
Better version of the Lickylicky you're using:
252 HP / 4 Def / 252 SpD Careful
-Payback/Foul Play (I think it gets Foul Play through BW2 Move tutors, not sure though...)
Pretty straight forwards. It's not Chansey, but it still passes wishes like a charm.
Heracross --> Sableye
252 HP / 120 Def / 136 SpD Careful
- Foul Play / Night Shade
Standard Sableye... if you can't beat 'em, join 'em, right?
Coffin and Queen look good, although i might go a physically defensive spread on coffin, since you have plenty of specially defensive walls (if you follow my suggestions). I also would put rest-->pain split, since you have a reliable cleric in Umbreon.
Last but not least is Ninjask, and could really use a rapid spinner to help your team out, preferably one with phazing, since nidoqueen will want help (and when is it ever a bad idea to have phazing on a stall team?) This brings us to: Blastoise.
Ninjask --> Blastoise
252 hp/252 def/4 spdef
-Foresight/Toxic (Foresight probably preferable due to the amount of status on your team).
-Surf/Scald (You have enough status with 2 WoW, Toxic on toise, and toxic spikes. Surf is superior).
-Roar/Dragon Tail (I'd go for roar again here, mostly because of all the Pokemon that like to abuse substitute in UU. Also gives you a chance to outpredict sub-cm raikou. With 3 layers spikes and stealth rock up, 1 switch in, sub, roar out, and switch in again takes enough health that it cant sub on the switch).
This would be a major overhaul, but i think it would be an interesting team.
Also, on a semi-unrelated note, Ninjask can be a very useful Pokemon in tiers up to Ubers- However, on your team he seriously lacks team support. None of your Pokemon could actually abuse Ninjask's boosts particularly well- Shaymin and Hera were choice locked, and the other three were defensive.
