Edo Tensei treasure and events ^^
I´m not sure if she can be pulled in other treasures as well

My opinion on Tenten:
- Early game: Decent ninja
The certain critical hit from chase are useful, moreover the 2* Tenten chases Repulse to High Float which is fairly nice, since this time of chase is not so common at early game (Sakura has Repulse to HF too, but Tenten is more suitable for offensive teams).

- Mid game: Average ninja
During the mid game, as the boom of 3* ninjas starts, Tenten starts to fall behind, even f2p players starts to get Iruka / GNW Tenten from events (around 900 coupons = 30 fragments, with discount ofc.)

-Late game: Low tier ninja

Tenten becomes more of liability in team, GNW Tenten is playable with right team since she has no battlefield cooldown.
