Hello, i recently got Shisui Susanoo as f2p and need help from more experienced players.

I don't need current lineup help (as the server is not even a week old) but rather what ninja to invest in and where i can find them.

1) With survival trial coins i'm thinking to farm Shikamaru chunin to 4* + break him, because he seems a decent support for shisui and what he

tries to accomplish. Is Danzo or someone else better to farm with trial coins to support S. Shisui?

2) I use all my moon coins for cave keys / power items, is there any ninja good for S. Shisui with moon coins that i should be farming instead? (Maybe Nagato?)

3) Is Edo Shin available in any events consistently (like treasure of the sage) / farmable with currency, or is he randomly put in events for redeem?

4) I save every single coupon for fuku deals, but if i find Anbu Itachi for cheap is it worth to get him early / mid game outside of fuku deals to support Shisui + make my life easier (to compete in arena+ pvp events).

5) Does Anbu itachi's bond skill activate with Shisui (Susanoo) card or it specificaly needs Shisui (Kotoamatsukami)?
