Try figuring out one that fits your playing style best. I've tried other peoples strategies, and I'm not as comfortable using them compared to when I make them myself.A decent one is, say, my prevention one. You'd need Shadowfire, Rikimaro's Surprise, Quick Charge, and Crushing Blow. Stand on the opponents card after you play Riki, then use Shadowfire. The rest should be obvious. This can take down a few teams with ease, so it's pretty good.
