It was curious to note from the pictured battles that both the Cthulhu spawn and the Mi-Go seem to have been composed of matter more widely different from that which we know than was the substance of the [Elder Things.] They were able to undergo transformations and reintegrations impossible for their adversaries, and seem therefore to have originally come from even remoter gulfs of the cosmic space.
–H.P. Lovecraft, At the Mountains of Madness

Luctor et Emergo

In H.P. Lovecraft’s mythos, the cosmic struggle has been going on for far longer than a human mind can fathom. In fact, it predates biological life on Earth. You can call it a miracle that out of the aeons, the Mi-Go managed to subsist despite the forces working against them. Hastur’s forces hunt them ferociously. The Star Spawn of Cthulhu seek to destroy them. The technologically advanced Elder Things are locked into a war with them so old as to be almost forgotten. Even humanity may start to take up arms against them. Yet, they survive, due to their adaptability, and because they can always send more from their Yuggoth outpost.

Mi-Go must be doing something right, otherwise they would have long ago been added to the list of races the universe has forgotten. Instead, they manage to take the spotlight at times, even outside The Yuggoth Contract cycle of Asylum packs, making an appearance on the box of Initiations of the Favored and now again on Curse of the Jade Emperor. And with good reason: Mi-Go can survive almost anywhere.

The more Mi-Go you have, the more powerful they become. Right now, it’s possible to make a deck that is more than half Mi-Go characters. A good portion of the remainder can be filled with Mi-Go related cards. Even though the Ancient Relics cycle of Asylum packs doesn't focus on them, a couple of its new cards work well with the themes and mechanics of Shub-Niggurath’s strangest sub-faction.

Take Harvesting Mi-Go (The Twilight Beckons, 11) as an example–a cheap Mi-Go that allows you to reuse a defeated character as a resource to bring out more Mi-Go. Forms of the Ether (Curse of the Jade Emperor, 39) completes the circle by bringing that card back completely. It also gives you some leeway to resource a card early on and still use it later in the game. Still, the Mi-Go have even more control over the life-cycle of your cards.

Quis Custodiet Ipsos Custodes?

Mi-Go Observer (Curse of the Jade Emperor, 38) helps you shrug off any threat against your Outer One forces. Take down one Mi-Go in a dedicated deck, and more will take its place. With a high ratio of Mi-Go in your deck, you can get up to five replacements for every individual taken down. Multiple observers allow you to respond multiple times, summoning an almost endless supply of space invaders. That should be enough to make anyone scratch their heads and wonder if taking one out is indeed the best option.

Outside the resilience this offers, the Observer also compensates for another blind-spot in the Mi-Go species: Terror icons. While the Mi-Go are able to handle themselves in combat, by gaining more Combat icons or using Ageless Mi-Go (Secrets of Arkham, 23) to resist damage, they previously had few options in dealing with mental trauma. The Observer gives them two Terror Icons, making it a very good base Mi-Go to buff and make a well-rounded character to send to stories.

For aeons, the Mi-Go managed to survive, despite the fact that almost everything tried to get rid of them. And all this time they have been content in silently observing. All the signs point toward them someday taking actions beyond merely watching… If none of the other factions of Call of Cthulhu: The Card Game manage to keep them in check, soon, they will take over…
