This monster works well in Rock Decks, since they rely on high DEF monsters. Also, its effect to attack directly makes it useful. However, you should use something to change it back to Defense Position.
This card would work well with "Super Crashbug", as it will be become a Level 4 2200 monster that (for only 800 Life Points) can attack your opponent directly.
Tip 2: Use "D2 Shield" to boost its DEF to 4400, then use "Inverse Universe" to swap its ATK with its now 4400 DEF, activate "Trap Stun", pay the 800, attack, and activate "Limiter Removal" for 8800 direct attack damage with just one monster.
You can pay 700 Life Points and use "Weapon Change" to quickly inflict 2200 direct damage for just the cost of 800 Life Points.
