right now, there will be a Fuku packs which have either 80 fragments of GNW Madara / Shisui or 128 fragments of Kisame...
Im not sure what ninjas or how many fragments of ninjas you have of these ninjas... however... if there will be available Kisame, I would go for remaining 52 fragments of Kisame (I saw 1 Kisame fragment for 135 cps?) which is cheapest 4* now, while being * strong...

In long run, I would go for 6p Naruto and GNW Madara as support... both BT and 4*... but thats gonna take a while since you are playing on new server... if you really wanna spend on this Fuku, I would personally go for Kisame if you dont have good P1 ninja... (if you have 100 fragments of GNW Madara or you can get them in upcoming events... I might go rather for Madara as he has more potential in future as a support ninja)...

But honestly, I might skip it, wait till 6p Naruto gets BT (he might be in some event or maybe even in Fuku) and go for him... as he is gonna be really amazing with only few specific counters, which are not gonna be really common on new server / new cluster
