No, no, no, nooooo.

Thunderbird lasts one (1) turn, and has basically zero impact on the Double rate of your Hime.
Fluffy lasts three (3) turns, and seems to have an EXTREME impact on the Combo rate of your Himes. Well, based on the entire... three times I've used Fluffy?

So yeah, please no. Don't even consider Thunderbird. Her on-use is awful. Passive is 'lright if you get multiple Stars on her, like every gacha Eidolon.
