dont be so dependant on sasuke. he becomes a crutch and every team you try to make, he'll be involved. everyone will always target him 1st anyway. if you have 64 seal scrolls, get 70 and use them. kage treasure is not coming out just yet and you're not even 80 yet. use them on tendo treasure and you might get shurado and/or ningendo. or you can wait till you're 70 and use them on sage, but you're gonna need some strong ninjas to help get you to 80. i also take it that you're more on the F2P side right?

i say use on tendo treasure. shurado, gakido, or tendo can be used for a while. if you get all 3 you can be golden. you just have to build up BP. and if you have gnw tenten, use itachi. Ao, orochimaru, and sasori 100 puppets are others in sage treasures.

saving for seal event is a good idea. having a healer is overrated if you can do enough damage quick enough or stop opponent from healing. but jigokudo, kakashi, gnw kankaro and earth main is a good team. i use for survival and finish with almost full health most times. if you want that lineup, let me know.

some of my best earth setups dont involve a healer. im at the point if i can do enough damage, the healer just gets in my way. b/c right now, sakura is one of the best healers we have. and with kankuro, he does re-summon his puppet, so even none gnw one is still good to use. and he does aoe damage, which is a help. you want to try to get as many ppl as low as you can quick. and if you can put ignite or poison on ppl, even more of a help. reason i say use seals on tendo treasure is because i have Ao and Orochimaru traitor, and dont really use them, I use Oro. in ranked, but thats it. also work on getting summons, cuz when you get gold summons, it makes combos longer and you have more potential to do more damage.
