Tendo is super rare meaning he comes at 400 scrolls and its either him or hashirama and jigokudo and shurado are basically useless ninjas at this point of the game and since you opened kage it means you are past lvl 70 so you dont need any pains now since you have gaara you can try to go in sage for sage naruto since he is one of the best f2p ninjas and he is no more then 180 if you are rly unlucky or you can continue to pull from kage but do only those 2 since others are * at this point of the game.
