I noticed something while looking through the cards - there are two forms of Gnatanothoa. This by itself is not unusual, there are two forms of several Ancient Ones. But, the ability to have six copies of some kind of Gnatanothoa seems to mesh will with the ability on the Out of the Aeons version which reads:

Action: Reveal another copy of Ghanatothoa from your hand to choose and destroy a non-Ancient One character. Then, shuffle that copy of Ghanatothotoa back into your deck.

So, you can destroy any non-Ancient One character for merely the cost of a card in your hand. There is no domain required, exhaustion, etc... Think of it this way, he basically says that any Gnatothoa card in your card can also be played as a (roughly) a zero cost event to destroy a non-AO character. With six copies in your deck and being shuffled back into the deck after each use, he ought to show up fairly often, and once you get him in place he's hard to kill being an Ancient One with Invulnerability.

So I'm wondering what the veterans think, is it possible to make a decent deck incorporating this? You've still got 44 other cards you can use to run your main strategy, but this provides you with bonus character removal that doesn't rely on wounding. If you did design a deck around this, what other cards would you consider a must-have? I'm thinking that Seeker of Mysteries is a likely prospect to get him into play, and maybe you could look at pairing with another faction that has cost reducers or ways to search for more copies.

Of course you also can still play the Lord of the Volcano version normally as well, who can have a huge number of Combat icons if your hand size is large.

I did a search and couldn't find any posted decks or prior discussion about Ghatanothotoa so I don't know if he's been overlooked or just silently agreed to be not worthwhile.

You can't have more than 3 cards with the same name in your deck. Doesn't matter if they have different sub-names.

Doh! My mistake then, I thought the restriction was 3 copies of the "same card".

So that idea's pretty much out the window then Thanks for pointing it out before I spent too much time trying to design the full deck.

If it makes you feel any better I did the exact same thing. Even drew up a deck concept around Cthulhu/Yog.

Things in the ground, Speak with the Dead, Hermantic Scholar, Opening the Limbo Gate, Magnus, All are One, Gathering at the Stones were all key cards in getting to see as many different copies of the guy as posssible. Actually, it was a decent enough deck. Fun to play. Too slow for it to of been really good, but it was fun.

Sadly though, as you now know... useless. Actually the deck still runs fine without G. Repalced it with Cthulhu and some lower cost cards for speed blocking and it turned out rather solid. Not great, but fun.
