Where and How do I use Lantern Yi Sang?

Hi there, I have difficulty figuring out where and how to use Lantern Yi Sang.

1) Where ( in which team)

We arrive at a point where there is enough ID in each status team where there is a "Best in Slot". The obvious thing would to put him in a Rupture team but it compete with W Sang and with Lantern Don + Tcorp Lu for aggro.

Or we can use him at lvl 1 for EGO resources but his slot is already used in other teams ( LCB in burn, Ring in bleed, LC/Spicebush in Sinking and BL/Pequod in Poise ). It may be worth it in Tremor and Charge team.

2) How (lvl?, SP)

Do I lvl up him for tanking or do I keep him at lvl 1 for the quick EGO resources. It is 2×4 resources or 2 from the least owned resources?

Do I him to be the lowest SP possible by taking only winning clashes and countering/EGO losing clashes? That way we could lose S2 in demand and nuke with in negative coins S3.

What are your thoughts how him?
