The Bottleneck Keeping Duplicator From Breaking

Several of the 13 avatars released in Gothic change the rules of engagement by manipulating the rules to their will. Magician plays without an Atlas, Corruptor says things aren't what they say, and Duplicator trades early resources for the powerful potency of making Uniques Elite.

Your spellbook and atlas can only contain matching pairs of Uniques, and you start with only two spells and two sites in hand.

You can only play with Uniques, but you get to, nay, must play two of each. Two Merlins? Double Morgana le Fay? Twofers on Ring of Morrigan? Cores by the pair? Two of any Warded Angel (e.g., Archangel Michael, Archangel Rafael, Archangel Gabriel, Archangel Samael) Wow!

Though flavorful, Duplicator requires conceding one-third of your opening hand as a buy-in to play with its power. This suggests Erik's Curiosa was aware of how powerful Duplicator's ability is and felt it needed a preemptive nerf for balance.

Beyond the financial hurdle of investing in a second copy of each Unique, there may already be a bottleneck more challenging for Duplicator to overcome: Unique sites.

Unique Sites

At the time of this article's publication, there are 59 Unique sites. Since Duplicator requires Uniques to be played in pairs, that means 15 of those 59 have to support threshold requirements for a pool of designs that are typically threshold-dense.

Below are all the Unique sites and the threshold they provide:

Of those 59, 24 do not provide, or have a condition for providing threshold. That leaves 35 threshold-providing sites. The best of them, arguably, are the tri-sites:

However, these apply pressure on needing to be placed in the back row, and when played in pairs, real estate becomes scarce.

We might have to accept the downsides of the four-element sites solely because they can provide much-needed threshold, but The Empyrean requires prerequisites to function. Avalon, Pristine Paradise, and The Colour Out of Space are likely temporary or unreliable, but are upfront.

Garden of Eden

The Garden of Eden is the only available Unique dual-site; it cuts off a strategic angle that Duplicator could leverage. The combinations available to Duplicator for heavy card draw are potent:

Single-Element Threshold Unique Sites

The breakdown is:

There are plenty of draws to each element. Fire might be the primary element to experiment with since it has the most threshold-producing Unique sites available.

Fire Uniques

has a few ways to recoup resources:

And many ways to control the Realm or swing the game:

Mana Matters

Duplicator is so cool, and it is easy to jump to all the awesome stuff it might let you pull off. For example, Chaoswish plus Kythera Mechanism casts infinite spells (always choose another copy of Chaoswish), so Ring of Morrigan can ping infinite times.

Epic spells, however, are sweeter if we can cast them. Our Atlas dictates what we can and cannot do. As a result of mediocre threshold production, Duplicator is likely priced into some supplemental sources in the Spellbook:

Shrine of the Dragonlord is a slam dunk. Two copies will go a long way to smoothing out threshold bottlenecks.

While going down another resource isn't where Duplicator wants to go, whatever Four Waters accelerates presumably generates the value back and then some.

The Four Cores — Aquamarine Core, Ruby Core, Onyx Core, and Amethyst Core — might also be necessary in the Spellbook. More support for Highlight Princess as a backbone piece in Duplicator.

The Philosopher's Stone is exceptionally powerful but only helps with mana production, not threshold. Depending on where your build of Duplicator goes, this might not be necessary, even if playing two could lead to insane turns.

Invest in as many copies of Erik's Curiosa as possible. Duplicator can play two, and they offer access to everything, including non-Unique sites for threshold fixing. Duplicator doesn't limit your Collection to only Uniques, so it is a potent place to solve your problems.

Again, two Highland Princesses effectively means four Erik's Curiosa in the Spellbook. Though Erik's Curiosa was ripped up, Pendragon Legacy could recycle whatever was tutored from the Collection.

Don't Get Duped-licator

Duplicator is fantastic and will only become more powerful over time with more Uniques released in future sets. Most of that will hopefully be in the form of Unique, threshold-rich sites.

I'm sure I've only scratched the surface of Duplicator. If this got your brewing brain churning, and you want to share your take on how to build it:
