I ran a few games with a similar build to sdougla2's Johktari Beastmaster. It worked really well. Those ranged attacks are a constant pain in the ass for your opponent since they are hard to stop and they constantly put corrode on the opponents creatures and mages.
I included a few nullifies and jinx to keep the mage where he is at the crucial points.

How do you play your opening turns? Ever tried to put the lair on FC? And might it be worth it to include an extra mana flower?
