your best bet, imho, since you went fully in gnw treasure, are naruto six paths or hokage minato or madara 10 tails (if we will ever see him in events at a decent price).

hiruzen is a very bad choice because it literally does nothing against comparable or higher powers.

edo minato too is a bad choice because his CD is simply too long and you just have to hope you don't lag to interrupt something (he doesn't give acupuncture/immobile/chaos/sleep, he delivers interrupt).
