You could try earth main with: gakido, hanzo, kk gaara; sage, kkgaara, minato; kkgaara, hanzo, nagato; gakido, hanzo, onoki

lightning: bee, hidan, danzo; any blitz

fire: sage(any), danzo, iruka; hashi, bee, sage naruto(any main basically);

and i could go on, and on.... actually, you have a lot of ninjas that are rare and good (lack of roshi, han, mei, kage tsunade, masked man from those currently impactful ones) so basically you can play any main (except water, because of mentioned earlier) and be really successful. The thing that limits you is basically you and your owned summons.
