Hmmmm. A real challenge.
Blue is quite bad, and the first color I dismissed. White has good tricks and creatures, but no two drops. Black is fine, and I built a BW deck, but it fell short of the RG one. Even the RG is a few cards short, so there are a few hard decisions to make. I decided to splash blue for the two gold cards, but then I'm greedy. Without the splash, you're left with playing a Nest Robber and Blossom Dryad to make up the creature count, and that's just bad.

Crash the RampartsThis brings the most power to the table, and certainly has the potential to win matches. It has a good long game, with Looter, Shapers, and Waker.
Things I don't like about it are the splash (it adds a lot of power, but there is no fixing excepting the single copy of
Unknown Shores, which you'd have to play), the curve is a bit on the high side and I'd prefer a creature or two more as the combat tricks can be dead cards if your creatures are dealt with. Also, only the raided Blasts to deal with big things, and even six damage sometimes won't get the job done.
Things I'm not sure about are: a
Sure Strike and the second
Crash the Ramparts instead of two
Pirate's Cutlass? I think the best would be a Cutlass and the Strike, but I don't know, Cutlass is just such a great card. In a league, I'd try out the
Sunbirds's Invocation and
Vance's Blasting Cannons, and I'd board them in here against slow decks.
The BW deck would need to splash for
Lightning Strike and Gorix, its early drops are unimpressive, and its late game (two Deacons) is weak. Its removal is situational, and it's not aggressive enough to make full use of the
Vampire's Zeal
