1. Doomsday Specter - I still don't think you can build a good deck around it, but I like it nonetheless.
2. Flametongu Kavu - great power/ability to casting cost ratio, great flavor text. Might even be useful in Standard someday.
3. Rith's Grove - gives me a R/W dual land!
4. Terminate - (almost) never a dead card.
5. Nemata, Grove Guardian - tougher than Deranged Hermit, faster than Verdant Force, and doesn't require a land sacrifice like Squirrel Wrangler. Makes a ridiculous combo w/ Gaea's Cradle.
Why Phyrexian Scuta doesn't make the cut - cast it with kicker and get Undermined - then you'll understand!
