Competitive Corner: Ojama ABC-Dragon Buster

Not that I love annoying people and providing them with terrible jokes and puns, but… I can't come up with a counter to that because on the contrary, if I can make someone cringe with a joke while doing finger guns, I've done my due diligence for the day.

So needless to say, I've always loved Ojama decks.

The Ojama cards debuted in Dark Crisis with Ojama Green and Ojama Trio, a trap card that actually bounced on and off the Forbidden & Limited List over the past few years. The word “ojama” is short for the Japanese greeting “ojamashimasu,” a kind way of apologizing when you're butting in on someone's personal space, or more specifically, their home. Even if you someone invited you, it's considered a nice gesture to apologize for the hassle you're imposing upon them.

Ojama cards - as evidenced by Ojama Trio - are only obeying the letter of the law, a play on the traditional apology as a mockery of it. The cards may seem polite on the surface, but whether they're invading your opponent's field zones with Ojama King, or switching their stats woth Ojama Country, how sorry are they really?

Probably about as sorry as Antonio Espinar was when he used his Ojama ABC-Dragon Buster deck to earn a Top 8 finish at the San Fernando Regional in Spain.

Legendary Duelists: Ancient Millennium brought us tons of legacy support for Ancient Gears, Crystal Beasts, and even A REPRINTED Worm Bait, FINALLY. Much of that support flew under the radar, but not as far under the radar as the White archetype has, even though the deck's eventually getting superb cards like this. All that said, one of the most powerful new releases actually serves as support for ABC's: Ojamassimilation. It's the only reason this mashup works.

If you've never played an ABC-Dragon Buster deck before, it's a surprisingly simple concept. You load your graveyard with A-Assault Core, B-Buster Dragon, and C-Crush Wyvern to summon a “free” ABC-Dragon Buster by banishing them. Buster Dragon can pop cards your opponent controls, or you can split your big Fusion into three smaller Machines in order to rinse and repeat the process.

Thanks to Union Hangar, two of the three pieces to that combo are never far from reach, but one problem's often plagued ABC decks through the history of their competitive use: consistently getting that third piece of your ABC-Dragon Buster to the graveyard. Antonio's build is innovative because it solved that age-old challenge in several ways.

The most noticeable answer to the problem is obviously Ojamassimilation. Start with Union Hangar or a Terraforming, Ojamassimilation, and any Ojama card, and you're already on your way to dominance: use Union Hangar to get either A-Assault Core or C-Crush Wyvern to your hand, then play Ojamassimilation to Special Summon whichever of the two you didn't search. Union Hangar's second effect kicks in when you summon either of them and attaches B-Buster Drake as a Union monster.

From there you could make a Link-2 monster like Proxy Dragon to send all the Machine pieces to the graveyard, or you could make Bujintei Tsukuyomi and add either A-Assault Core or C-Crush Wyvern to your hand to yard it that way. As great as that is, it's really just the bare bones; it doesn't showcase the real power of Ojamassimilation.

Keep in mind that Ojamassimilation banishes Ojamas from your field, hand, or graveyard, so Bujintei Tsukuyomi really is your best friend right out of the gate. It doesn't require you to run multiple copies because the first one provides you with your start: food for ABC-Dragon Buster and Ojamassimilation.

In an ideal world, you could start the duel off by fielding Bujintei Tsukuyomi, yard three Ojama monsters, then use Ojamassimilation to field the remaining three Machine monsters in your deck for a flurry of a million Link monsters, but that's not totally needed. Antonio used Ojamassimilation to consistently field what he needed for ABC-Dragon Buster, leveraging Bujintei Tsukuyomi on both sides of the play.

No Bad Cards!
Technically, the Ojama Normal monsters are some of the most useless cards in Yu-Gi-Oh. At least by themselves. Objectively speaking they're just Normal Level 2 Beast monsters with 0 ATK, but Antonio was determined to make the most out of them. I already touted Bujintei Tsukuyomi as a method of dumping your hand on the way to your best monsters, but even without Bujintei Tsukuyomi, there are other ways to find success.

Option one is Dragon Ravine. Anytime I'm maxing out on Terraforming, I look for ways to play multiple Field Spells so my starting hands aren't flooded with duplicate copies of cards that I can't use in tandem. Drawing multiple copies of Union Hangar is like drawing multiple copies of Pot of Desires: one is fantastic, but that second copy's just worthless. Dragon Ravine turns your Ojama monster into a yarded Destrudo the Lost Dragon's Frisson, the second piece of the puzzle for this strategy.

Destrudo was Antonio's answer to no fewer than three distinct problems. The first is, “Ok, what do I do with these mismatched combo pieces?” The second is, “How do I make Black Rose Dragon to destroy everything and OTK,” and the last is, “How do I get my Union Hangar?”

Antonio played Black Rose Dragon because mid-to-late game situations and duels where you go second can often turn into uphill battles when you're working against an established field. Annihilating the rest of the cards on the board, then establishing an ABC-Dragon Buster can be lethal for your opponent. But about that third problem…

Any monster – even an Ojama – can pair with a Dragon Ravine to get you nearly all the way to ABC-Dragon Buster thanks to Ancient Fairy Dragon. Just use Dragon Ravine to yard Destrudo, then revive it from the graveyard with any monster you summon to make Ancient Fairy. The Level 7 Dragon pops Dragon Ravine to get you Union Hangar, and from there you can search A-Assault Core or C-Crush Wyvern and Special Summon it with Ancient Fairy's effect.

Union Hangar kicks in, attaching B-Buster Drake to your Union monster, and when you Link Summon Proxy Dragon, and suddenly you have all three pieces for ABC-Dragon Buster either in your hand or already loaded to the graveyard. So even in the worst of situations – games where you start with a Dragon Ravine and four Ojama monsters in your hand – you can still make something useful.

Defenses! More Defenses!
When you're speeding through your deck and using Bujintei Tsukuyomi as your pièce de résistance, all you can really hope to end with is a few set cards. Even once you clear the field with Black Rose Dragon, you won't have the cards needed to build up an unbreakable defense in the form of multiple hand traps and several facedown cards. But Antonio played a handful of traps to supplement his Machine strategy.

Hand traps fall by the wayside here because your goal is to make Bujintei Tsukuyomi on Turn 1 every game, so actual trap cards are better than hand traps. Solemn Strike goes without saying - if you can clear most of the field with ABC-Dragon Buster, a well-timed Strike easily becomes the last nail in your opponent's coffin.

Torrential Tribute's a Little Different. Because Dragon Buster can split into its three Union pieces - all of which net you card economy when they're yarded - you can clear your opponent's field with Torrential and come out on top. That would be a perfect time to “apologize” to your opponent: seems courteous when you clear the whole field and still have as much card economy as you did before.

One of Antonio's wisest decisions was maintaining the proportions of his build. It's tempting to load your deck with multiple copies of cards like Ojama Pyjama so you always see it reliably. The problem? You really don't want to see it in your opening. Similar to the hand trap quandary, Ojama Pyjama won't help you on Turn 1; you'd rather draw into it after you resolve Bujintei Tsukuyomi, so one copy's perfect.

You could make the case for adding different Ojama cards, but many of them hold you back more than they actually help you. You need to Normal Summon Ojama Red to trigger its effect, and you need to wait a turn before you can use Ojama Duo. Ojamagic makes Ojamas a major standout in this deck, but Antonio kept Ojamas in an ancillary helping role rather than letting them take over as the central focal point.

Since the deck's so consistent, there's not much I can offer to make the deck that much better. Effect Veiler may not be the best choice, but then again, any hand trap becomes more powerful when you're sitting behind ABC-Dragon Buster. There's one super silly combo I came up with that involves Dragunity Dux, Dragunity Phalanx, Chaofeng, Phantom of the Yang Zing, and Egotistical Ape, but boy does that sound awful when I say it out loud. Antonio really put together a fantastic, highly polished strategy that's worth playing right out of the box.

Just remember: beat your opponents before they beat you.
