1 Talents and Illusion Crow pet, can change Karin for Kabuto when doing survival for summons.

Tobi can be bought for trial credits that you get from survival trial at the exchange npc, Gaara is a bit harder if you don't pay, he shows up in black market for 100k per 5 fragments and in survival, also you can get lucky and draw him.
