How to use GAC Planner
Overview
GAC Planner helps you plan Grand Arena attacks: load rosters, set up the enemy defense, find counter suggestions, and optionally build a battle plan before you attack in game.
Mode (3v3 / 5v5)
Use the toggle at the top to switch between 3v3 and 5v5 format. This changes how many enemy squad slots you plan for.
Your roster
Your ally code is loaded from Account settings and used to fetch your roster. Scout defense imports your GAC defense from the previous round—if you changed your defense since then, scout again or edit squads manually.
Mark units and datacrons as used in defense or attack so they are excluded from counter suggestions for other squads.
Enemy defense
Enter the opponent's ally code. Scout imports their defense from the previous round—it may not match their current setup if they changed it since then. You can also build squads manually with + Add squad, assign datacrons, and fill unit slots.
Counters
Click Refresh to fetch counter suggestions for each enemy squad. Adjust threshold and minimum battle count, and sort by win rate or sample size.
Use toggles for two-shot searches (paid), datacron matching (including level depth), and requiring relics on your roster. Per-squad refresh and enemy datacron level toggles refine individual squads.
Click a counter row to mark its units as used in attack.
Battle plan
Enable the battle plan toggle, then use To battle plan on a counter to assign it to an enemy squad. Track success or failure, and see an aggregate win chance. Planned units are hidden from other squads' counter lists.
Tips
Expand or collapse counter blocks using the label next to the refresh button, or by clicking the enemy squad row. Two-shot rows list follow-up attacks after a losing first hit. Some features require a subscription or guild access.
