The strategy is to pack
Radagast on the Freeps and outrun the deck.
If you get everything right, you can stop a double or 2 with, like, 5 minions out. But, I'll admit, the chance is pretty slim there.
The point really isn't to stop anything. Its goal is to cycle, and if necessary be able to pack somewhat of a punch. Typically Swarm Style with Runners and
A Shadow Rises should be effective in halting a double.
