Best kit build for 3v3

Here's a detailed guide for Kit in Brawl Stars, focusing on his Cardboard Box Gadget, Overly Attached Star Power, and Health & Shield Gears:Kit’s Cardboard Box Gadget
What It Does:Kit’s Cardboard Box Gadget allows him to disguise herself as a cardboard box, blending into the environment for a short period of time. When activated, his becomes immobile, but other players cannot see him unless they are within close proximity.
TipsUse for Ambushes: The Cardboard Box gadget is excellent for sneaking up on opponents. Hide in a corner or behind obstacles and wait for enemies to come close. When they do, pop out of the box and surprise them!
Escape: If you’re in a dangerous situation, use the gadget to blend in and wait for the heat to die down. You can also use it to trick enemies into thinking you're gone, while you plan your next move.
Team Strategy: Coordinate with your teammates. When Kit uses his Cardboard Box, she can distract the enemy long enough for teammates to take advantage of their positioning or focus on objectives.
Important Notes:While disguised, Kit cannot move or attack, so pick the right moment to use it.
The gadget can only last for a few seconds, so timing is essential.
Also as a gold 3 kit, attack as much as you can until they are not in your distance then jump.
