Skip or summon?

Honestly?

Would you have any use for Any of the Brave units? I don't.

For the Fury banner mostly likely we will see

Myrrh
Eldigan
Exalted Chrom.

I am skipping this banner and the legend banner so i can blow everything on getting +def Myrrh :D

On the legend i might pull for a hector since i need it for my Myrrh.

The only CYL unit I recall seeing on any of the legendary banners was Lyn, because they wanted to force her onto every single banner. Lyn hatred aside, I'd pull for Marth. He's a beastly dragon slayer, with a better version of Regnal Astra and better Windsweep.

I did a calculation on the probability of finding L.Marth. Approximately 1 in 44 red orbs will reveal him. If you have 60 orbs, you can summon probably 13-15 reds, which means if you try pulling with that number of orbs on three legendary banners, you'll probably get your desired focus unit once. 1/3.

What's more likely to happen is that you get either Lene or Swordhart. 60 orbs is maybe 1-2 pulls less than what the math expects to be able to find a red focus, so the chances are decent for finding ONE focus unit, and then 2 times in 3 it's not Marth.

Also, the orb prices you're being offered on the CYL banner are poor. Four focus units of all colours splitting 3% means one of the highest numbers for expected number of orbs to obtain a focus unit, all other things being equal. (Ex: compared to three focus units without shared colour splitting 3%) I have recommended to everybody against pulling on this banner. The units will certainly reappear, and probably often in the next few months.

Your call.

Only you can decide if you should pull based on your needs. Here's my mini review:

Red pool - L. Marth is good for a single copy, but if you're interested at all in Arena then you're not going for him over L. Hector. Lene and Swordhardt have little value outside single copies as they have nothing for fodder save Lene's Safeguard.

Green pool - This is the roughest of the banner. Gunnthra is both the worst scoring legendary and the worst legendary for fodder, so has no value outside one copy unless you like the character. Vector is Vector, but he can't salvage this pool. Alfonse's best fodder is now in the permanent pool on a 4* available unit, and Def Smoke is... whatever. Wait for February if you want to pull for Vector and skip green here.

Blue - The best pool on this banner. Fjorm is Fjorm and additional copies of her are always welcome for every piece of content. You can never have enough Nephenees as Wrath remains one of the best B skills in FEH, and the hero herself is one of the best blue units. Brave Lucina has 3 pieces of great fodder, and while the unit isn't what she once was, she still remains one of the best AA support options. If you're interested in Arena, this is an extremely good pool to snipe.

Colorless - Grima remains our only colorless legendary and about equal to L!Ike as an Earth option. Faye rarely comes back these days as a focus unit, so her appearance here is most welcome. Spring Kagero has Lethal Carrot and a Bond skill for fodder and is arguably the game's best dagger unit at the moment. While not as good as the blue pool, this is another solid pool to pull from.

So based on your personal needs, avoid green, pull on blue and colorless as needed, and stay in red only long enough to get an L. Marth to be honest as Lene is arguably not even as good as the game's 4* available dancer in her pool and Swordhardt is... unnecessary albeit fun and lacks anything for fodder.
