Since Sergeant Electro is susceptible to attacks, it's ideal to have these cards in your back row.
These cards would greatly help Sergeant Electro to make it not susceptible to attacks.
You can equip 7 completed to Sergeant Electro since it's a Machine-Type monster. Permanent 700 increase to attack or defense is a great increase in the current meta.
Destroy your opponent's monster with a very high attack by equiping Metalmorph. Besides from the 300 boost to its attack and defense, it gains half of the attack of the attack target during the damage calculation.
Rare Metalmorph is another card that can only be used to Machine-Type monsters. Activate this card to increase Sergeant Electro's attack by 500. It also has an effect that could negate spells that targets the monster that is affected by Rare Metalmorph's effect.
