Look for Axe Grinder, Underground Brigand or Kobold Warbeast in your opening hand. You can also keep Ground Shaker.
Start with a mountain in front or to the side and go to the same side as your opponent. The following lands can be a mountain or a desert, depending on what you have in your hand. Place a desert at the well so Wind Soldier can collect and so Flash Salmon has more reach.
Use Rakoan Chieftain's effect with your small creatures to take out your opponent's bigger creatures. Gain control of the wells, then push up and go face.
This deck got me from rank 10 to God rank. It's fun to play and works pretty well, give it a try! :)
