Its less effective in the end for 2 reasons : Eidolon effect and weapon's assault skill.
Tyr is a damage dealer, she works more or less like Siegfried (use her buff + burst on stun, not entering in detail here)
The less she is buffed by eidolon and weapon, the less she is effective.
Its different with Sol (and even beelz), who are in a team for utility reasons.
You can build another team alongside your water team, with Sol + Tyr + Baal (thunder SR from story mode) + Beelz
Soul advices for this team are more or less the same than your water team.
Ofc this is true for long term objectives. At the beginning, when your main eidolon is Diabolos, and your weapon grid is filled with whatever you found, you can put whatever you want in your team![]()
