Danzo is seriously under rated and a very fierce barrier ninja. 3 rounds of instant chaos, can protect ninja from dying and a decent AOE that hits hard. Plus his chase causes immobile. Much better than Edo Zabuza or Zetsu or any of those ninja. Mei is seriously a power house. AOE poison control plus a barrier for water/fire, yes please. Darui is a staple in Ay lineups, and mixes well with a ltg sustain lineup. Buffs water and Ltg and attacks twice every round? He is very good still and will remain good. Killer Bee 7 Sword is that one ninja you will always see being used. He is end game and even Samuel and other power houses use Bee. Definitely a ninja you want. The 10 pull ninja are strong, and I will honestly tell you to pull in Kage first, then when you are done snaggin the ninja you want/need, start pulling GNW. Trust me, barrier ninja are very powerful in this game, and there will always be a need for them. Do yourself a favor, and pull in Kage.
