Excellent idea! My only suggestion would be to maybe add the Temple of Mystery? I believe that's what it's called. The ability to scry 1 could literally save this combo. But still great deck idea!
Keep up the good work.

If you have any suggestions for this deck, please let me know. I'm always willing to hear from other players. Thank you!

I seriously need help with this one. This deck was very intense to make and I need serious help to make it better than it is now. All advice or comments on it will be greatly appreciated.

If you have any ideas for this deck, I'm always looking to improve upon it. All advice is welcome and needed. Thank you!

I would also recommend Fencing Ace. A fencing ace with a few Ethereal Armors on him. Oh God, talk about damage. You could also add in that enchantment that makes a creature unblockable and whenever they attack you scry 1. Would make the game your's instantly.

Why not have both? I see no reason why not to have both cards in the deck at the same time? Just means you'll have two horrible monsters for your opponents to deal with instead of 1 Emrakul. Also, if someone exiles Emrakul with something like Merciless Eviction for instance, you'll still be able to pull out Progenitus.

I'm anxious to see what other players think of this deck. Please post any comments you have about this deck. Thank you!

I'm not sure how you could do it, but I would highly recommend more Ethereal Armors. Those things are crazy and they'd get really large really fast.

Artifacts are kinda an interest of mine. Perhaps I could suggest some things I'd make changes to.
I would suggest many more Etched Champions, Stoic Rebuttals are easier than Cancel, Go for the Throat wouldn't affect a lot of your creatures, especially if you included Mycosynth Lattice. Fabricate is always a good card to have in an artifact deck.
Basically, I would take out a bunch of the single cards you have and stack up on some of the cards you already have.
I would also remove Phyrexian Ingester. He seems a little out of place here.
I have a few artifact decks. Feel free to look at them if you'd like to get any more ideas.

If you have any suggestions for this deck, please let me know. I'm always eager to hear from other players.

Primeval Titan also exists... <__<

You'd also keep the deck's theme. The titans live outside the walls, in forests and hilly areas, not in the artic, or near the sea.

My only advice would be to remove the blue and replace it with green. Much better green giants than blue. Trust me. I've checked.

What would recommend me to remove for such a card?

I like a few of your suggestions. Wayfaring Temple, Rootborn Defense, and Selesnya charm. My only problem would be that I don't know what to take out to put those cards in. Can you help me with this?

Oops. Looked at Experiment One's p/t wrong. So, I'll take him out of the combo, but it actually does work. Mycoloth's saprolings all enter at once, which means they all check to see if they're p/t is higher than Cloudfin Raptor at the same time. Since they're all stronger than it, they all trigger the evolve ability.
I had to check and then double check, but it does work.

If you see any problems or things you'd change to the deck, please let me know. I'm always willing and eager to hear from other players in the MTG community.

Yeah. Sorry for completely screwing up your mana. I actually came up with an idea to have massive saprolings and infinite evolve counters.
Experiment One, Bioshift, Elite Arcanist, Mycoloth, and a Master Biomancer are the cards you'll need. If you can think up a deck around it, I will gladly put some input on it.

Alright. I actually see what you're doing now. Didn't realize you were going to add in Purphoros. Excellent idea if that's what you're doing. Thought you were only going for spamming tokens and swinging with them later.
I know you're feeling about Theros. Looks pretty fun. I know I can have several ideas about what I could make.

So, I've got a few recommendations for the deck.
Crucible of Fire, of course. Hellkite Charger, allows you to 1) pop out more dragon tokens 2) attack with the tokens you've already made this turn 3) have the biggest smile on your face when you can attack more than twice. My only other suggestion would be something that lets you add red mana to your pool till end of turn. Don't really care how much, but running a dragon deck can be difficult if you're short on mana, so adding red to your pool can seriously help out in a bind.
But it is your deck. Do as you please.
