The concept is pretty simple. Use Wild Research so that the Rabid Wombat is eventually 15/16 banding, flanking, first strike, haste, trample, flying. I usually kill my opponent with Aura Gnarlids before I get to that point, but a win is a win.
The 5/17/13 random card of the day is Species Gorger. If you know of a combo or decklist involving this card, feel free to share it.
I have a few decks that combine Cavern Harpy with CIP effects. I would definitely replace the Harpy with the Gorger in some of those decks. It will be much easier for the Species Gorger to get through when it is returning [a CARD]Bone Shredder[/CARD] or Nekrataal to your hand every a turn.
