As the Rummy

 * Since your bullet choice is quite random, don't turn on override. The inceptioner bullet might need its auto turret.
 * Just fire straight at the enemy, as you don't know what type of bullet is coming next.

Against the Rummy

 * Drone tanks can easily get its drones behind the Rummy and kill it.
 * Bullet spammers also work, as they can outpenetrate the Rummy.

Trivia
Its expanding trap is the largest trap in the game, perhaps the largest ammunition in all playable tanks
