Tamamo is amazing, but Arts team rosters can be difficult to fill out with viable teams. If you didn't pick up Nero (4* saber) in this event, she might be worth considering. She is story locked, has a tripple guts skill for survival, lots of self heal, and an AoE Arts NP.

Lancelot is a boss regardless of team comp, but he lack survivability. Medea Lilly can be extremely helpful for stall teams - though she overlaps heavily with Tamamo. Caster Gil fills the Arts Crit role that Tamamo doesn't if you are making use of that niche. Rider Martha is a verstile Buster or Arts team debuff clearer.

I would also consider Tristan if you don't have him. He has two Arts cards and fits fairly easily into an Arts team with Tamamo. He has a team wide evade skill (similar to Merlin's team wide invulnerability), Since it's a skill, Tamamo can reduce it's cooldown. This same skill also removes mental debuffs (like charm). He has a 50% NP charge skill to make use of his Quick ST NP with ignore evade. Finally he has a buff remove skill in case of enemy invulnerability or other team demise ensuing buff.
