Centur-Ion Deck Guide: How to Play

Playstyle and Win Condition

Centur-Ion Cards

There are two key Monsters for the Centur-Ion archetype that enables their access to the Level 12 Synchro Monsters. The Centur-Ion monsters, particularly Centur-Ion Primera and Centur-Ion Trudea, are almost always needed on the field, and can stay there as Continuous Traps that can be Special Summoned on to the Main Monster Zone through Quick Effects.

Primera acts as the primary searcher and Tuner, while Trudea can increase its Level by 4 upon being Summoned from being a Continuous Trap. Gargoyle II acts as additional Synchro Material for Level 12 or even Level 8 Synchro Monsters.

The Spells and Traps of the archetype enable the Deck's playstyle. Emblema Oath puts a "Centurion" monster as a Continuous Trap on the Spell/Trap Zone. The Field Spell Stand Up Centur-Ion! lets the user Synchro Summon even on the opponent's turn, which is what makes this Deck hard to respond to.

Centur-Ion Bonds can easily refresh "Centurion" monsters and make them Continuous Traps again from the GY. Centur-Ion Phalanx protects your important monsters by banishing them temporarily, and Special Summoning them later.

Bystial Engine

For some access to Level 10 Synchros, consider running a couple of Bystial Monsters to keep the opponent on their toes, especially if they run LIGHT and DARK monsters. Magnamhut and Druiswurm are fine on their own, but players can consider the rest of the Bystial Engine.

Hand Traps

Because of how self-sufficient the Centur-Ion cards are in terms of resources, players can slot in as many interruptions as they want to make sure the opponent does not get to play the game properly; hence, the sheer number of Hand Traps in the Deck Recipe. Each one is tailored to gain massive advantage, or to deny the opponent resources themselves.

Extra Deck

"Centur-Ion" only has two Synchro Monsters, and both are Level 12.

Centur-Ion Auxila is the boss monster you want to summon first, as it protects your backrow first while face-up and active. On Special Summon, its effect triggers a search effect for fellow "Centur-Ion" cards.

"Centur-Ion Legatia" protectsmonsters from battle destruction if they have 2000 or less ATK, and provides a draw and a card destruction effect simulatneously. It also helps set up future "Centurion" monsters for play to bring out more Synchro Monsters during the opponent's turn.

What makes the Deck very dangerous is the combination of one of the "Centurion" Syncho monsters, and Crimson Dragon. This one card enables the easiest summoning of the more powerful Level 12 Sycnhro Monsters.

Cosmic Blazar Dragon, Cosmic Quasar Dragon, and Shooting Quasar Dragon all have powerful negates tied to their summons. Red Supernova Dragon is the game-ending summon which gets more powerful with each Tuner in the GY.

Boss Monsters

	Crimson Dragon
	Crimson Dragon is a crucial card for this Deck, as it provides access to all other Level 12 Dragon-type Synchro Monsters so long as there is another Level 12 Synchro Monster on the field to be used as a tribute for the effect.
	Cosmic Blazar Dragon
	The best of the Stardust Dragon-esque Leve 12 Synchros, Cosmic Blazar Dragon provides negates for card effects and summons, and it can even end the Battle Phase. However, you can only use one before this card is banished until the End Phase; choose wisely on when to use this card's effect.
	Red Supernova Dragon
	A more aggressive Level 12 Synchro Monster, Red Supernova Dragon gets an ATK boost for every Tuner in the owner's Graveyard. It is immune to the opponent's card effects, and can banish all cards the opponent controls should they launch an attack or activate a monster effect. This is can end Duels quickly once summoned.
	Centur-Ion Legatia
	So long as Centur-Ion Legatia is on the field, monsters you control with 2000 ATK or less cannot be destroyed by battle. On Special Summon, this monster provides a draw and destroy the opponent's monster with the highest ATK. It can also set up a future play by placing a non-Synchro "Centur-Ion" monster on the Spell/Trap Zone.
	Baronne de Fleur
	So long as a Deck has access to Level 10 Synchro Monsters, Baronne de Fleur will always remain a popular pick. Its omni-negate, once-per-turn card destruction, and ability to Special Sumon is makes this card extremely flexible.
	Chaos Angel
	If you have the necessary requirements, players do not even need an actual Tuner Monster on the field to Synchro Summon Chaos Angel. It banishes a card whenever it is Special Summoned, and depending on the materials used to Synchro Summon this card, it gains effects that make it harder to remove from the field.

Tearlaments

Tearlaments having options to mill cards from their Deck to the GY might very well affect a Centur-Ion player as well, and when they manage to set up properly with various boss monsters with potent effects, it can be extremely hard to break their board.

Going first against Tear, your starting hand will give you a shot to stop their combos. Going second against, pray that you have enough cards to break their defenses.

Best Cards to Tech Against Centur-Ion

	Evenly Matched
	One of the best ways todeal with Centur-Ion is to wipe the field during their most vulnerable. Evenly Matched, when timed right after the Battle Phase, can banish all but 1 card from the opponent's field.
	Heavy Storm & Harpie's Feather Duster
	Part of the combo of Centur-Ion is putting up the Main Deck "Centur-Ion" monsters is to have them be in the Spell/Trap Zone, then once summoned from there they can immediately Synchro Summon. Backrow threats like Harpie's Feather Duster and Heavy Storm should deal with them before they can be summoned.
	Skill Drain
	With Skill Drain active, no monster on the field can trigger nor activate their effects. This deals from their Main Deck monsters to their Extra Deck monsters, turning them into simply monsters with respectable to really high ATK stats.
	Maxx "C"
	The Special Summon combos for this Deck is crucial to get into their Level 12 Synchro Monsters, thus Maxx "C" remains the best card to go against Special Summon-heavy strategies like Centur-Ion.
