The Harmony Mechs are a series of LIGHT Machine-Type monsters first created by ZeroChill and introduced in the set Wrath of Divinity and included further support in Ancient Justice. Most Harmony Mechs require the player to mill their cards to use their effects. Some cards in the Harmony Mech Series activate upon being sent into the Graveyard.
Due to their low ATK power, Harmony Mechs tend to stall the opponent using cards such as Balance of Harmony and Harmony Mech 6-A2 until you met the conditions for cards like Harmony Mech O-P and Harmony Mech 0-TK. While you have a vast amount of Harmony Mech monsters in your Graveyard, you can Summon Harmony Mech Alpha to thicken your Deck a bit to prevent a Deck-Out as well as increase it's ATK. Harmony Mech Beta's effect shines while you have Harmony Mech monsters in your Graveyard: You can negate your opponent's Special Summons for the price of returning 1 Harmony Mech in your Graveyard to your Deck.
Strengths & WeaknessesEdit
Harmony Mechs are capable of strengthening the advantages of their user. Most Harmony Mech's effects are powerful for their cost. You can increase ATK or defend a monster for the cost of milling the top card of your Graveyard. However, most Harmony Mechs have very low ATK and DEF for their Level, putting them in danger of destruction from battle. Harmony Mechs have recieved needed support in the Ancient Justice Set, creating more options to defeat your opponent, thus Harmony Mechs are no longer mildly supported. However, There is a good chance Harmony Mechs may be able to lose through a Deck-Out situation, so be sure to be able to get prepared against Decks such as Plagues and Chaos as they can hurt the Deck.
