I started playing a monster resilient deck which personally I haven't seen anyone else do yet. The harpy eggs act like a resilient unit since they hatch the next round. The Ekimmara gets resilience, and the riders get resilience if you lost the round. So I usually go all out to win the first round, but the harpy eggs and ekimmara(s) give me a huge boost in the second round, even if I lost card advantage. In the second round I play the riders so that in case I lose I still have cards for the 3rd round. If I think I will lose the first round, I instead play the riders first and then the ekimmara's in the second round to clench the 3rd. Sometimes though I can just blow the opponent out in the first two rounds.
