Another great post and I strongly recommend reading ecoinstant's 12 tips whether you are a newbie or have been playing for a while.
In the Gold league, my preference to play would be Pyre's speed deck for offensive and for defence, use Lorna for the shield and super Bila if there is enough mana.
Also Unicorn Mustang + Prismatic Energy to counter the Magic decks, especially when Ruler of the Seas is in play. You can also throw in a failed summoner for a 3rd Magic Reflect if you want to annoy your opponent....lol
