Gearlocs position themselves in starting positions according to their Atk form as normal. They use their Dex and Atk stats to move and attack critters on the mat, using their normal Atk form. Skills and Backup Plans may not be used.
On a critter turn, all critters in the rolled Lane will activate and simultaneously move on top of an adjacent existing stack (removing them if none exists). Then one Gearloc will activate, then Critters again, then a second Gearloc, etc.
