Last week we mentioned that Pegasus dueled Dr. Crowler in Yu-Gi-Oh! GX, and this week we'll look at the Doctor himself - he didn't get his Ph.D in Dueling for nothing, as he'll be happy to remind you! Crowler might be as quirky as Pegasus, but his Deck was anything but, centered around Ancient Gear Golem and proving to be a big challenge for Jaden during the entry trials for Duel Academy.

After Jaden's beat him, Crowler antagonized him out of revenge, but eventually came to treasure his students dearly. By the time of Season 4 rolled around - which was sadly never dubbed in English - he even tried to keep them from graduating, resulting in another Duel with Jaden where he learned that Crowler had upped his game: Crowler could now fuse three Ancient Gear Golem into Ultimate Ancient Gear Golem!

In real life, Ultimate Ancient Gear Golem only needs a single Ancient Gear Golem plus any two other "Ancient Gear" monsters, so it's much easier to Summon… though it's still tricky. Once it's out you have a 4400 ATK monster that deals piercing damage and stops your opponent from responding to its attacks with spell or trap cards, and in the event it's destroyed, you'll bring back the original Ancient Gear Golem.

Today's deck musters the support cards Crowler received in Legendary Duelists: Ancient Millennium, reprinted in last year's product-hover id="214980". You'll either Summon Ancient Gear Golem or Ultimate Ancient Gear Golem by quickly amassing the Fusion materials, and you've got some other options just in case.

To Summon Ultimate Ancient Gear Golem, you need the original Ancient Gear Golem. It's a strong monster but it has one annoying line of text that makes it tricky to use: "Cannot be Special Summoned".

Some Ancient Gear support cards can bypass this restriction, but it's still a pain. If you control no monsters, Ancient Gear Catapult can destroy another card you control to Summon an Ancient Gear monster form your Deck, ignoring the Summoning conditions. Ancient Gear Frame can do that too, but your opponent has to destroy it with an effect, so it's much better to use its first effect to either search out Ancient Gear Golem or any card that mentions it.

Unfortunately, we only have three Ancient Gear Frame and searching it out requires jumping through some hoops. Ancient Gear Wyvern can search any Ancient Gear card when it's Summoned, and while it's tempting to search Ancient Gear Frame, it's also great to grab Ancient Gear Box. Adding Ancient Gear Box to your hand lets you search out any other Earth Machine monster with 500 ATK or DEF, and fortunately Ancient Gear Frame has 500 DEF. Ideally you want to search it, so you're only running two.

Once you have your Fusion materials, you'll need something to fuse them with. Three Ancient Gear Fusion are excellent, since you can use monsters in your deck if you have either Ancient Gear Golem or Ancient Gear Golem - Ultimate Pound on the field.

Ancient Gear Golem - Ultimate Pound can also search out Polymerization when it's destroyed, so one copy will suit us nicely. To make Fusion Summons more consistent, you've also got the Obelisk Force's main monster from Yu-Gi-Oh! ARC-V, Ancient Gear Hunting Hound, which can fuse monsters with its effect.

Even without Ancient Gear Golem, you have other options to Fusion Summon. Ancient Gear Megaton Golem only has 3300 ATK but you can make it with any three Ancient Gears, and if you use either Ancient Gear Golem or Ancient Gear Golem - Ultimate Pound as material, it gains the same number of attacks. If your opponent does get rid of it, you can spring Ultimate Ancient Gear Golem straight from your Extra Deck.

If you have four Ancient Gears in your hand, you can borrow the Obelisk Force's most powerful monster: Chaos Ancient Gear Giant, which trades the usual Ancient Gear effect for immunity to Spell and Trap effects, negates the effects of the monsters it battles, and can attack all your opponent's monsters.

Ancient Gears aren't particularly complicated, but they can dish out some serious pain unhindered. While I largely limited this deck to support cards used by Doctor Crowler, there's several other Ancient Gear cards from different themes, including the Obelisk Force's cards and some that even combine with Gadgets that Yuri used in Yu-Gi-Oh! ARC-V. Whatever the direction, it's always a blast to pummel your your opponent with massive machine!
