I like it, but why Sparks and Photons? Put some Dragons in 'der.
Sparks can give you just that bit of extra punch in the end of a fight, and photons can stay in the game for a bit, if you have nothing else to play. Most likely, you'll immolate whatever you get anyway.
Since this type of deck has very limited quanta, it's not a good idea to add dragons, except Maybe a fire one. I'd still rather keep an extra golem to increase my early game chances, rather than drawing that, since you'll never get that amount of quanta. You'll most likely not even have enough to play that shield... the shield is there for those just in case scenarios. I'd rather be safe mid game than sorry in the first draw.
Here's the deck I used in the AI3 Challenge (http://elementscommunity.org/forum/index.php/topic,1874.0.html). It can win in 4 turns.
That looks pretty nice, but I wouldn't put a graboid there. You'll most likely need that earth quantum for the golems, which are likely to be in play long before you get that graboid, and probably multiple copies of it. If you have no earth quantum, and your mark is earth, would you really keep a dead card in your hand for three turns and not buff your golem when you can?
In your deck, I'd probably remove that graboid, and possibly a nova too... eitI'd either put two graviton fire eaters in their place, or two deflags. Probably deflags, since I like permanancy control, for those moments where you need it.
Does your deck work well in T50?
Hey, I actually like this one! I tried, and it worked pretty well in T50! I'm making this deck on my main account.
Yeah, this is my favorite T50 deck too. I can outrush those anoying life decks on a lucky draw, where the shrieker deck usually failed misserably.
