[Machine/Synchro/Effect]Armory Arm is the first Machine Synchro monster introduced to the game. Its ATK and DEF are not impressive, but its effects makeup for the lack of attack power. It's not always the card, it's how you play your cards. Armory Arm also appears to be based on the Armor monsters used by Valon in his duel against Joey. Each Armor monster is a separate piece of armor that attaches itself to Valon as his body becomes the actual monster in play.
1 Tuner + 1 or more non-Tuner monsters
Once per turn, you can either: Target 1 monster on the field; equip this card to that target, OR: Unequip this card and Special Summon it in Attack Position. While equipped by this effect, that target gains 1000 ATK. If that target destroys a monster by battle and sends it to the Graveyard: Inflict damage to your opponent equal to the ATK of the destroyed monster in the Graveyard.
Synchro summoning Armory Arm is not easy as some decks lack combos to special summon low level monsters. The best decks to Synchro summon Armory Arm are decks that focus on special summoning low-level monsters for Synchro summons or XYZ summons such as Junk, Planet, and Synchron. One simple play is to use Junk Synchron's effect to special summon any level one non-Tuner monster from the graveyard to quickly summon Armory Arm.
Armory Arm has two very notable effects. First, once per turn, you can equip or unequip Armory Arm to any monster on the field, and the monster gains 1000 ATK. If your opponent has a much stronger monster on the field, then you can find a way out of the problem by equipping Armory Arm to a weaker monster. A weak level four monster equipped with Armory Arm will be able to take down a much stronger level seven monster. The effect is even more effective when equipped with a strong monster with high ATK.
Furthermore, Armory Arm's second effect is extremely devastating as it inflicts damage to your opponent equal to the destroyed monster's ATK. Destroying an opponent's monster with high ATK will at least reduce 1/4 of an opponent's Life Points. It can either give you early advantage in the game or make a huge push to win the game during the latter stages of the game. It has many potential game ending plays with Black Rose Dragon, Black Luster Soldier Envoy of the Beginning, and Shooting Star Dragon.
All in all, Armory Arm is a really good Synchro monster that can make big plays that will affect the outcome of a game. Synchro decks definitely want to take advantage of Armory Arm's abilities to change the game in their favor. Its ability heavily damages an opponent by inflicting additional damage to your opponent equal to the ATK of the destroyed monster. Armory Arm can take over any game with an iron fist!
