You shouldn't even need Kaiden. The other five should be more than enough. Are you running on auto or on manual? As long as you use your moves properly should make mincemeat of them.

i use manual.   i do use my moves properly (i think).  its the counter that gets me

best way to deal with them is crowd control them with prevokes or stuns before they can get the counter up

A few questions: 

What's your Stun/Regen/Immortal look like? 

How close are you to being done Lydia? I'm a big fan of loading up your Faction Wars champs with your best possible gear if you can afford the swaps when we're doing FW21 and close to being done with Lydia.

The biggest issue I'm seeing here is gearing. Supreme Kael should greatly lessen the need for accuracy on your champs given the A3, but Madame and Zavia are too slow. We are especially going to need Madame faster to time stripping Valk counterattacks.

Another option I see is Psylar in a stun set, between her and Madame you should be able to keep Valkyries from wreaking too much havoc. I could see taking Lanakis out for Psylar and running something like:

Psylar in stun

Blind Seer in regen/immortal/some healing with lots of HP since we're going to be relying on her for shields/revives.

Supreme Kael/Zavia/Madame.

I am not close to finish FW for Lydia  

skinwalkers all 3 stars excet 19 and 21

DE all 3 stars except 21

undead all 3 stars excet 21

rest are around level 14-18 (but not to sure).

for stun/regain sets i usally do not keep. so i do not have alot of them  Now i guess that was not a good idea.  immortal i do have a fair amount of pieces but most are 5 star peices. Iam maxed out in gear.  not enough space for the number of ssets lol.   i do have the following banner i can switch with kael

i

but i would lose res and def but get more hp, attack and speed

one other option you have is vizier ovelis. you can use his a2 into his a3 to block buffs on the majority of your opponents (ideally all of them, but his debuff spread is a bit of a crapshoot). it will likewise be a matter of speed; you'll need him to get 2 turns before any opposing valks get their first so he'll need to be decently fast and you'll want to avoid using any buffs.

I would guess that one of the problems is Madames rather low Accuracy...you might want to raise that...

how high should i go for?

i think hes right since madame has 2 lots of cc technically which acts similar to a stun/provoke debuff, she might be enough cc for you to throw off the counter attack buffers long enough to start taking 1 or 2 down, im not sure about accuracy for factions but its the same as dungeons then probably 210 + for stage 21, 250 probably a safe bet.

ok i work on that.

Thanks all for the advise

No need for that much acc. 180+ is fine.

ill take his word for it :P 

if we're able to keep inc acc/dec res up, then it's not as big of a deal

otherwise I'd like to get closer to 250 accuracy actually, IIRC the waves are quite RES heavy
