Solid deck, +1 from me!

I've built my fair share of dragon decks so I have a couple of suggestions.

I did playtesting with it and I found that the 2-drop slot is a little crowded. I also noticed that Voyaging Satyr wasn't entirely necessary because you already have the Garruk Wildspeakers to untap your lands. Personally, I don't think that amount of ramp is necessary considering your highest cost card is 5 mana. If you were running something like Balefire Dragon or Dragonlord Atarka, that would make sense but with this particular list, it seems like it's being wasted.

For this reason, I would take out the 2 Voyaging Satyr and add something like Sarkhan's Triumph, Shaman of Forgotten Ways or Taurean Mauler (or any 3-drop card to make sure there's no gap in your curve).

That's just my 2 cents, you can always look at my page for inspiration if you like, I have plenty of Dragon decks on there.

Also, I would recommend Feed the Clan in your sideboard, it's fantastic against Burn decks and other fast decks. They're trying to kill you quickly, so if you cast this when you have a big creature, you'll gain 10 life, which is extremely useful against those kind of decks.

Anyway, best of luck! This looks very solid!

Feed the Clan seems like a good option, I can probably take out Ratchet Bomb for it.

You are probably right about Voyaging Satyr.

Some alternatives I thought about:

1. Lead the Stampede, Hunter's Insight or Domri Rade for card draw.

2. Big Ramp Targets like:
   Genesis Wave, Dragonlord Atarka, Hellkite Tyrant, Primeval Titan, Inferno Titan or Deus of Calamity.

3. More mainboard burn/removal: Searing Blaze, Beast Within, Lightning Bolt.

What do you think ?

Would Signal the Clans be good in this deck ?

I decided to use Obstinate Baloth in the sideboard over Feed the Clan as it provides a solid body and does double duty against Burn/Aggro as well as discard (Liliana).

Frontier Siege can be potentially a good addition to the deck as both modes can be relevant.

Duskwatch Recruiter  ^Flip seems good here (as a potential replacement for Scaleguard Sentinels) as a mana-sink that can help draw cards or beat-down and reduce the cost of dragons when flipped.

Maybe Domri Rade can be an additional source of CA ?
