Enhance Monster

Enhance Monsters are a new type of Monsters made by Smooth Operator. They rest in the Extra Deck and they have military green card frames.

To  Enhance Summon, you need 1 monster equipped with only 1 Equip Card (by that, it is not only an Equip Spell Card, but also Union Monsters, monsters that can equip on other monsters [see "", as well as the "" archetype] or even Normal Trap Cards that can be treated as an Equip Spell Card [like ""]. Those cards are sent to the Graveyard and you already did an Enhance Summon.

Enhance Monsters have a Level.

Enhance Monsters also have a built-in feature called Arming. Arming is, once per turn, you can place 1 Equip Spell specifically and place it underneath the Enhance Monster, gaining all the Equip Spell's effects. Arming can also be performed by card effects, if they state so. For example, if you Arm a monster with "", it will gain 500 ATK and prevents your opponent's monsters from changing their battle positions.
