Christmas 2021 Event Revival (US)/Challenge Quest

Well all in the title. I was trying to beat CQ, but didn't managed to do it fairly. I've tried it many times with a little different team-comps and have no possibtive result. So...

In last try I've used this team:

In this CQ enemy were killing my servant before they even use NP, so I have to use all 3 my scopes, and try to annihilate tham as fast as possible despite I prefer to use stale\semi-stale playstyle. But, well this team had a really good result (compered with my others):

Killed 2 enemies and almost break hp bars on two remainings... but still I have to use my Command Spells at the end... that's why I'm saying that I didn't beat it fairly, but... well, atleast I did it somehow, so lore is lore. Especically since I'm in their hell...

I only hoping that I get my CS back before next CQ...

Also...

...even with command spells I have lost part of my servants in second time...

But well I got this:

So it was worth it...

Thanks to @Muhammad Abdul Aziz Habibi , for you Cu, and also since I've finished it, you can change his CE, also, btw, you're right about it, since Iron-Willed Training don't really help against berserkers, so... that's is.

And this fight got me thinking about... what about servant with AOE nope skills? I've used Merlin, David and Mash (she don't have it, but... well she is one of the best if not best def support, so I guess she is considered), but that wasn't enough, so... where I can find more servants with similar skills\nps? Only f2p or avaiable during next year, please (in order to not to cross with my main targets)...
