can you post a picture of your roster? it'll be easier to give advice if we know who you've got to work with.

I believe that team is gonna need a stun target, like Skullcrusher. Or you need Ally Protection, like Toragi, to more effectively tank the stun.

What you're looking for is this https://deadwoodjedi.com/speed-tunes/double-warcaster-v2/ but you want to book Demytha's A3 to only a 4 turn cooldown and you use her for one warcaster slot. 

The Ally Protection Version is here: https://media.discordapp.net/attachments/716468726324789281/951950021467729990/RSL-CB-MythCaster-UNM-turn-order.png This one tanks the stun with Toragi Ally Protection (or any other Ally Protectors on the same cooldowns)

Maybe easier, if you have Seeker and High Khatun, is this team: https://deadwoodjedi.com/speed-tunes/myth-seeker/

Thank you for your help i will try it out the ally protection version as i dont have seeker nor skull crusher 

You can also do it with Gnarlhorn, who I see you have in your vault. He can tank the stun with Unkillable and survive. :D

Alright will do
