I would still be on RG Dragons for this weekend if I were able to play in any events. I am not, so I will share my list. I wasn't too happy with Arbor Colossus last week in the main, as it's just too narrow. I also think that format will be evening out a bit so that there won't be an extreme amount of mirrors. I think that there will be more control decks this week than there were last week, which isn't too great for us, but we still have some powerful cards against them. I would just play my same maindeck from Syracuse to be honest.

4 Elvish Mystic

4 Sylvan Caryatid

4 Courser of Kruphix

4 Thunderbreak Regent

2 Ashcloud Phoenix

4 Stormbreath Dragon

2 Dragonlord Atarka

3 Xenagos, the Reveler

4 Draconic Roar

3 Crater's Claws

2 Roast

4 Temple of Abandon

4 Wooded Foothills

2 Mana Confluence

2 Rugged Highlands

3 Haven of the Spirit Dragon

6 Forest

3 Mountain

There are two different sideboards that I was interested in trying out this week, but with no event this weekend I didn't really do any testing.

2 Plummet

1 Chandra, Pyromaster

1 Nissa, Worldwaker

2 Destructive Revelry

1 Outpost Siege

1 Arbor Colossus

2 Seismic Rupture

2 Hornet Nest

2 Wild Slash

1 Roast

This Sideboard is just using the tried and true cards. I'm playing a second Plummet over the Den Protector from States since it just wasn't good for me at all. We still want access to an Arbor Colossus, but it could just be anything really. The mirror will be a little less prevalent, but I think it's still good enough against the Mantis Rider decks to be worth considering.

My other idea is a bit of a transformation sideboard.

4 Goblin Rabblemaster

2 Plummet

2 Destructive Revelry

2 Seismic Rupture

2 Wild Slash

2 Hornet Nest

1 Roast

Rather than leaning on Planeswalkers to pressure the control decks, we can try Goblin Rabblemaster. Cards like Bile Blight and Drown in Sorrow are both very poor against us, and being a little lower on the curve will help to overload their removal. There aren't very many cards that are good against Goblin Rabblemaster that are also effective against Thunderbreak Regent and Stormbreath Dragon. Hero's Downfall and Ultimate Price are already pretty well taxed, and if we get a chance to steal the initiative with a Goblin Rabblemaster they can easily die to a stream of threats afterwards.

Goblin Rabblemaster is still pretty poor against Courser of Kruphix decks that don't incentivize us to bring in Roast, so that's something to keep in mind.

GL this weekend everyone, and jam them Dragons.
