I absolutely don't know which Servant should I pick from the free ticket, so I hope someone can give me an advice. Tomoe is my waifu btw, but I'm interested in other opinions too...
When this comes to NA, I will definitively pick Tomoe as well...
Your team has Quick Merlin, maybe Nyalter will be a good option.
OG Nero is a good arts AOE survivalist.
Lalter is the best non 5* Lancer in the game, in bustercrit and has a good AOE NP.
I'd say go for the waifu, because Waifu top priority.
If you want go for gameplay route, then a quick servant would be good. Atalante Alter is a good option, she's a Zerker Quick ST. You also have Gilgamesh caster, who can help on art crit teams so Lancelot Saber is another good choice.
