earth main, kk gaara, bee, sn..
main shields as well as bees
or wind main with same team
water main, sn, iruka, ao

but I find fire main, sage naruto, sage jiraya, iruka to be a powerful combo.... round 1 interrupt, round 2 sage naruto and fire main skill, round 3 sjiraya and main skill
round 4 iruka interrupt ...Noone usually survives past that round

dog of hell summon works with fire main line up above
