Hello Pojo Fans,
Artmage Diactorus is one of two Fusion Monsters in the archetype and the final card we’ll review this week.
Needing an Artmage monster and Medius as materials, Medius searches Patron upon summon and can Special Summon it, with Patron acting as a Fusion Spell on the field. Fusion Summoning this isn’t hard, even if you don’t go this route. Solid stats for a Level 8 Fusion, and it comes with the ability to change the position of a monster on the field (if possible). With 2800ATK you are likely taking the bulk of monsters down if you can spin them to defense. Even with Link Monsters not being affected by this first effect, the opponent would have to get up to a Link-4 to out-attack Diactorus.
Wouldn’t be an Artmage monster if it didn’t have a “4 or more different Monster Types on your field” effect, and for Diactorus, the Quick Effect it gains allows you to negate a card or effect activation and destroy the card in question. Love to see a boss monster in an archetype have once per turn, Quick Effect negation, it is something pretty much all archetypes need in a monster nowadays. Diactorus replacing itself with a Medius from the hand, Deck, or banished area upon Diactorus being destroyed will setup another Fusion Summon on your turn, or, at the least, put two bodies on the board to protect (as long as you have another Artmage Power Patron).
Negation and destruction once per turn with the ability to interact during the opponent’s turn is great for a boss monster. Needing the three or more different Monster Types on your field follows the theme of the archetype and functions as a balance. With each Main Deck Artmage able to be Special Summoned in some way through the archetype, and Medius being able to be Normal Summoned without taking up your Normal Summon when paired with the Field Spell, this Fusion Monster is an easy-to-come-by weapon for the archetype. Gives you back at least one monster when destroyed, with the potential of two, and, can do a once per turn change battle position to a monster on the field to enable easier attacking. Strong Fusion Monster with the negation as long as you fuel it. When off, it does kind of sit out there without protection though, so be careful.
Advanced- 4/5
Art- 4/5

The week ends off with one of the soon to be three Fusions dedicated to the Artmage archetype: Artmage Diactorus.
Diactorus is a Level 8 LIGHT Fairy Fusion with 2800 ATK and 2500 DEF. Strong stats, a good Attribute, and a solid Type. Fusion Materials are Medius the Pure and any Artmage monster, so easy to do (don’t worry, we’ll review Medius next week). First effect lets you target a monster on the field and change its battle position. Would have been nice as a Quick Effect to work with Nerva on the opponent’s turn, but guess they don’t want the board nuke to be that easy. The Quick Effect that’s actually on this card is one you likely won’t want to change, however, as if you control 3 or more different Monster Types and the opponent activates any card or effect, you can negate the activatiton and destroy that card. An omni-negate is always nice for an archetypal boss monster, even if it needs a little extra setup, but Konami has wanted to steer away from easy omni-negates seemingly, so it makes sense here and goes with the rest of the theme. Finally, if this Fusion Summoned card is destroyed, you can Special Summon a Medius the Pure from the hand, Deck, or banishment, replacing itself with Medius to get you to what you would need to summon another copy of this, no graveyard reviving cause Medius already does that on his own. HOPT on each effect is fine. Diactorus is a good end board piece for Artmage, and it should be easy to have this setup with Finmel and Graflare to make all their effects live at least. While you’ll likely only keep 1 on the endboard, he’s solid enough and there’s enough room in a typical Artmage Extra Deck to warrant 2.
As for Genesys, it’s a rare case of a card that has an omni-negate that isn’t too hard to summon and setup, and no points attached to it. No wonder Artmage does well over there.
Advanced Rating: 4/5
Genesys Rating: 4.25/5
Art: 4.25/5 Medius has his school uniform now.

Closing out our Artmage coverage is the official sub-boss (though arguably main boss) of the Artmage archetype, Artmage Diactorus, a level 8 LIGHT Fairy Fusion monster. It’ll only take Medius the Pure and any Artmage monster, so Medius summoning Artmage Power Patron will be able to make it almost immediately. Even if Artmage Power Patron is out of commission, you still have several ways to fuse like Artmage Masterwork -Succession-. Importantly, listing Medius as a Fusion material will let you use Fusion Deployment as well, which is an excellent boost in consistency considering Medius alone makes it with the combo above. Diactorus’s stats are decent enough for a level 8 monster, with 2800 attack and 2500 defense; OTK power shouldn’t be a huge issue in Artmage since it’s fairly good at swarming.
Diactorus has 3 hard once per turn effects, the first being the most puzzling one– it simply targets any monster on the field and changes its battle position. This is an effect you’d see on a boss monster from 2005, but believe it or not, it does have one intended purpose. If you summon Nerva the Power Patron of Knowledge with its alternative summoning condition, it’ll be in Defense Position, so this effect is useful for changing it to Attack Position. Aside from that, it’s also a convenient effect to replace with Nerva’s nuke in case you wanted to save your other effects. Diactorus’s second effect can only be used if you control 3 or more monsters with different types, a Quick Effect to respond to an opponent’s card or effect activation, negating the activation and destroying the card. Simple but solid negate! Of course, the unfortunate drawback is being forced to field 3 different types for it to be live, which is highly unlikely by the time Nibiru the Primal Being is ready to spring on you, but at least it’s not too difficult to set up. Ideally, you’ll end on Diactorus, Artmage Graflare, Artmage Finmel, and Artmage Litera, with Artmage Power Patron ready in the Graveyard to be revived by Litera and Fuse into Nerva. Diactorus’s final effect is the obligatory recovery in case it bites the dust, triggering if it’s destroyed while Fusion Summoned to Special Summon a Medius from your hand, deck, or banishment (curiously, not the Graveyard, but then that would be too easy I suppose). This’ll obviously bring out another Medius who will summon another Artmage Power Patron and, big surprise, summon another Diactorus to replace the one that just died, making up for the lack of protection a bit. Diactorus is a solid boss monster for what it is, but in true magic school fashion, it’s basically useless alone, so you’ll need to have a good grasp of combo lines to play Artmage effectively.
While Artmage has been struggling to break through the Advanced meta even with hybrid builds with Fiendsmith and K9, pure builds have been making modest gains in Genesys thanks to being largely unhit. So yippie! Maybe their future support will shake things up.
+Solid negate on a monster that’s extremely easy to make
+Effectively replaces itself if destroyed
-Needs 3 types to use its negate
-Can’t revive Medius from the Graveyard
Advanced: 3.75/5
Genesys: 4/5
Art: 3.5/5 You’re a wizard, Har– I mean Medius.
