Hello!

In my opinion, it is better to make a full team first for you to have a regular team that you cạn use for your daily battles. You already have Kakuzu [Earth Grudge Fear] fully breakthrough so you only have to buy great support to him such as Itachi [Edo Tensei]. Deidara [Akatsuki's Creation] is a good choice also but usually, he's the position 1 ninja while Kakuzu [Earth Grudge Fear] is the support position 2. For Minato Namikaze [Edo Tensei], you'll be like back to zero since you will need to breakthrough him first before he became a decent position 1 ninja, together with Nagato [Edo Tensei] and Sasori [Edo Tensei] or other ninja combinations that you would like. Kimimaro [Halloween] is a great ninja also as position 1, an instant nuke at first-round killing or dealing a massive amount of damage instantly together with Hiruzen Sarutobi [Edo Tensei] and Asuma [Wind Blade]. This is only my opinion and the rest will depend on you. Thank you.
