Either way you shouldn't be actively trying for a ninja like him. If you happen to get him in boxes with the main goal of spending for the redeemables, then cool. If he does come to tendo treasure, then it isn't a wise choice unless you already have the Kage and GNW SRs, itachi susannoo, and edo hashirama. Having him in BA rebate is fine since the focus is leveling for power and you get him as a bonus. Spend your resources wisely unless you're a whale and can do whatever you want.
