Great show as always fellas.
Gavin, you mentioned something along the lines of cheap bots/etc on MODO, did you know there are free bots there? I don't use Magic Online, but I have heard there are bots such as MTGOTradersFreeBot and FreeCardBot, that will give you x commons per month, for free(or something like that). Not sure if they still exist since the transition to v.3, but it is definitely something to look into.
I do agree that Black Lotus is overrated. I Cube draft, and it definitely leads to some crazy plays, but if you're playing a Juzam Djinn 1st turn it will probably get StP'ed. It is the most expensive card in Magic for a reason, but it definitely doesn't let you win on the spot(I know it can, but that is beside the point).
Dare I say Extirpate is overrated?
As for underrated, it's pretty hard to do, as it is much, MUCH easier to hate on some popular cards that people play.

I guess I'd have to go with a pet card of mine, Crackleburr. That thing can definitely out of hand.
The card drive is an awesome idea, and I will be emailing Tom for the details.
I guess this is my entry for the Endrek Sahr deck. It started as a



devour/token deck with such classic hits as Delraich and Goblin Bombardment. The green was a tiny splash for Sprouting Thrinax(I wanted to live the dream of sacrificing at least 1 thrinax to cast Delraich

). I cut the red to focus more on green for Mycoloth and Eternal Witness, so here it is(it's Extended legal too):
3 Endrek Sahr, Master Breeder
4 Marsh Flitter
3 Murderous Redcap
1 Tar Fiend
4 Llanowar Elves
4 Wall of Roots
3 Fertile Ground
3 Mycoloth
3 Kitchen Finks
4 Eternal Witness
2 Primal Command
3 Garruk Wildspeaker
6 Swamp
13 Forest
4 Llanowar Wastes
Kind of a mana-rampy/rockish/token deck. It can pump out some creatures to devour to the elementals, or just overrun with garruk. Shriekmaw could be of some use in here too, as a way to kill a dude or kill a dude AND get some guys from Endrek Sahr. Something die? Witness it back.
Primal Command kind of adds +2 to each of your creatures. A toolbox approach could work with the creatures as well. There may be too much acceleration in the deck, not quite sure.
Of course the manabase could be made better, but I kept it simple and less costly with basics+pains. Garruk's the most expensive card in the deck, and with him being less played now, prices have gone down. And digital ones are relatively cheap too.
