** Higher Level Machina that either have an effect to discard another Machina/Machine to the GY such as "[[Machina Air Raider]]", "[[Machina Irradiator]]", "[[Machina Cannon]]" and "[[Machina Fortress]]" or want to be discarded to the graveyard due to their graveyard effect such as "[[Machina Ruinforce]]", "[[Machina Megaform]]" and "[[Machina Citadel]]". These Machina effect varies between removal and negate effect of "[[Machina Fortress]]", "[[Machina Citadel]]" and "[[Machina Ruinforce]]" to replacing current Machina such as "[[Machina Air Raider]]" and "[[Machina Irradiator]]" and "[[Machina Megaform]]".** Lower level Machina that help protect, mil, search and swarm the higher level Machina.

*The original "Machina" playstyle was focused on [[Special Summon]]ing "[[Machina Force]]" with the effect of "[[Commander Covington]]"; this playstyle had become obsolete with later "Machina" support and boss monsters, which are far more effective and poorly synergize with this original playstyle. Some "Machina" monsters are also [[Union monster]]s, but these effects only play a minimal role in the current "Machina" playstyle.* Generally, [[EARTH]] "Machina" monsters are high-[[Level]] monsters with two common effect patterns: Special Summoning themselves by [[discard]]ing [[Machine]] monsters, and [[destroy]]ing the player's Machine monsters (or [[trigger]] their effects in response to their destruction) for advantage. The two main "Machina" boss monsters with [[field]]-holding powers are "[[Machina Fortress]]" and "[[Machina Citadel]]", whose effects reflect these two patterns: "Fortress" can be Special Summoned from the [[hand]] or [[GY]] by discarding Machine monster(s) whose total Levels equal 8 or more, while "Citadel" can be Special Summoned from the GY if an EARTH Machine monster is destroyed, and has a [[Quick Effect]] that destroys the opponent's monsters by destroying one of the player's Machine monster.

* The [[DARK]] "Machina" monsters have more diverse supportive effects. "[[Machina Possesstorage]]" revives "Machina" monsters in the GY, "[[Machina Unclaspare]]" is an extender that also [[mill]]s a "Machina" monster, and "[[Machina Resavenger]]" is an [[ATK]] boost [[hand trap]] with self-recovery. The DARK "Machina" boss monster, "[[Machina Ruinforce]]", is a 4600 ATK [[beatstick]] that can Special Summon itself from the GY by [[banish]]ing Machine monsters in the GY; it can [[negate]] [[card effect]]s during the [[Battle Phase]], and can Special Summon banished "Machina" monsters when destroyed.* Their spell and trap varies from searching, protection and recycling. "[[Machina Redeployment]]" help dump higher level Machina into the GY to search more Machina. "[[Machina Overdrive]]" help bring out a Machina right from the deck and serves as recycle, "[[Machina Armored Unit]]" and "[[Machina Defense Perimeter]]" both serves as protection and recycling.* The "Machina" archetype's overall game plan is a relentless beatdown strategy, constantly dumping and reviving easily Special Summoned high-ATK boss monsters to end the game as quickly as possible. While the Deck has little to no protection, it is capable of dodging targeted effect with their self-popping effect and either replace themselves or reviving another "Machina" monster from the Deck or graveyard, or blow up the opponent's field with the effect of "[[Machina Citadel]]". However, the archetype's reliance on discards and destroying the player's monsters gives it a poor grind game. This archetypal weakness is typically mitigated by hybridizing the Deck with another Machine archetype that provides a much stronger grind game, the two most common ones being the "[[Gadget]]" and "[[Infinitrack]]" archetype.

* The archetype relies on its [[GY]] to maximize its limited grind game; if all monsters [[sent]] to the GY are [[banish]]ed instead, such as by the effect of "[[Dimensional Fissure]]" or "[[Macro Cosmos]]", the archetype becomes completely incapable of grinding and will easily burn itself out with its discard and self-destruction effects. In addition some Machina monster also need their card to be sent to the [[GY]] to activate their effects which means these card are extra effective against the archetype.
