No real strategy, though knowing when and how to use the RE's does help. On a golem when it's big enough, IF you think it won't get killed. Otherwise, save them for getting rid of opponent's creatures, such as nasty evil Oty or Druid.
Comments if you want. It's about as lean as I can make it, and yes, Gemfinders are better than Towers.
