This is a tough battle,because its 1 against 2. Its Susake against Gaara and Kunkuro.You should defeat Kunkuro first since he's easy and annoying espically with his puppet.Worry about Gaara second since he wont come and attack you directly but will attack u with his sand, dont get to close to Gaara while ur fighting Kunkuro or attack with his close range sand attack.When u defeat Kunkuro,attack Gaara next, Gaara should be easy to defeat,but that sand wall can get on ur nerves.Continue the same pattern through round wo and u will win.
