I would reduce it to 30 cards and reduce the amount of Otys to 2-3. Maybe some more attack power would be good too.
1. Cut it down to 30 cards like Chapuz said. Less cards = better draws.
I'm well aware that I need to cut this deck down to 30 cards (or just above), but i've never known how to do so. That was one of the reasons I posted this deck up; to get feedback.
2. What exactly is the synergy of this deck? I can see fire eater, but that's a pretty weak synergy to tie two elements together. Generally, duo decks should have a very strong or potent synergy.
The Graviton Fire Eaters are the main crux of the deck, and are also the main point of synergy. There's also the way that Fire has a tendency to reduce the opponent's creature's creature's health, making them easier prey for the Otyughs.
3. It seems very slow, and 6 unupped otys (with 2 momentum) will hardly eat anything. Consider more fire shields or CC cards. Those synergize nicely with oty.
It is quite slow at the moment, one of the main things that needs fixing. The Otyughs are a decent form of CC once they get going, and they're the cards i'm planning on upgrading first anyways. Which CC cards specifically were you thinking of?
In a duo deck like this, why run fire spirit? Gravitron fire eater completely outclasses it because it can survive weaker CC spells.
Fire Spirit was initially there as a placeholder until I got more Fire Eaters, and I sort of ended up leaving them there as Otyugh fodder or emergency Fire Eater replacements. I should probably take them out, thanks for the reminder.
Anyway, based on that feedback, here's Version 2:

I'm not sure how this will work, so if this is wrong, don't hold back on telling me so.
