Good team for saber dadcelot

Saberlot - Tamamo - Zhuge Liang

Hans is good too as he can improve the critical damage of Saberlot. Saberlot is a pretty self-sufficient character so the best supports for him are those that improve his damage and survival

Sup' ,

For dadcelot you need : a support to keep him alive + boost his damage + a star generator even if he is pretty decent to it in order to keep the crits on his art and quick cards
It can be like :
Best team :
- Dadcelot + Tamamo no Moe + Waver (spam spam NP)
- Dadcelot + Tamamo no Moe/Waver + Shuten Doji (a bit spicy)
Or lower cost version :
- Dadcelot + Hans + Cu
- Dadcelot + Hans + Hassan of the Cursed Arm

Aside from the standard suggestions, hans, waver and tamamo (that are literally suggested for every team), I would suggest Kiritsugu as the star generator. He has several arts cards to create arts chains with lancelot and generates a bunch of stars with his multiple-hit attacks. He also has a targetable taunt that can draw hits away from Lancelot if need be.

For super F2P options, Hans, Mash, and Ceasar are the ones I used. Been pretty much using those with ceasar using that on use 20 crit star CE we got from the rashamon event with the combat uniform.

Dadcelot is largely an independent unit. As has been said the one thing he lacks are defensive abilities. Waver is ideal mostly because he's waver. The other slot can be Tamamo, another waver for offense, Hans for both offense and some defense, and mash even for more defense. Tamamo is ideal as her np reduces the skill CD of all of Dadcelot's skills all of which are somewhat vital to his niche.

Realistically, you do not need a star gen if you can get one 2030 on preferably waver. Between those 8 stars, Lancelot's ability that gens stars every turn, and whatever other stars you might generate through attacks, you should have enough. In fact if you take Hans as the second support and give him 2030 as well you'll be rolling in more stars than you know what to do with

I tried out Emiya Assassin with Waver + Saberlot.. The amount of Star Gen was insane.
