Well my immediate problem is the lack of dual-lands. Also I would suggest some Recollects would be useful too. But right now Im gonna turn things over to the local master, Roger, aka Crusader.
Hi there, long time no chat, but with so much time to kill at the moment, Laura asked if I could give my critique, so first things first.
Dual lands, I stress these greatly, LLanowar wastes (sp) and Overgrown tombs. Wastes are relatively cheap and work great if you can't get four tombs, however, I'd run four of each.
James was right with the birds, both elves (deep shadow and Llanowar), and maybe even signets for speed. One thing I'd never do is run the Lair lands, the Rot-Farm, in any constructed deck unless it was running Kudzu or any form of Angry Kudzu.
Why not eliminate the 2x's and cut the fat. By dropping some of the cards that really don't interact with the Primary conditions of the deck, you can afford to drop 4x of the ones that really matter.
Cut?
Teferi's puzzle box stuck out as unneeded. With only 1 copy it serves little than a one in a million influence to the game, and even then its an annoyance as it can greatly help your opponent. Now its great with Underworld dreams but thats not the exact method of the deck.
By cutting the Teferis we can safely chop the dreams. This gives us room for three. If you want disruption, why not try Persecute, possibly one of the greatest black cards in the block right now as with 90% of the decks running two colors, its not hard to pull off a turn three Mind twist and ditch their whole hand.
Next I'd probably ditch Seedborn Muse. Your creatures are big and stand for themselves, I assume the muse was so you could swing all out without being vulnerable. With token production though minimal, you should be able to let the big guys brawl safely while the lil' ones stand staunch in the back for support.
Now with Biorhythm as a win condition, what could is Woebringer? Yeah it kills their creatures, but with Woe being able to show up as early as turn 4, and biorhythm much later, it slightly hinders the rhythm (pun). With little token production that shows up rather late, and little that shows up early, I think the woebringer without recursion help could hurt you more than help.
I'm rambling so let me crack it down.
Creatures:
3 Verdant Force
3 Elves of Deep Shadow
3 Llanowar Elves
3 Woebringer Demon
1 Plaguewind
4 Golgari Guildmage
Spells / Other
3 Persecute
4 Putrefy
3 Golgari Germination
4 Scatter the Seeds
4 Fists of Ironwood
3 Doubling Season
2 Biorhythm
Land
4 Llanowar Waste
9 Forest
7 Swamp
Ok heres a relatively cheap and easy build that can revolve around your method of beatdown and biorhythm. With the mana from elves and the Guildmage you can generate a pretty good lockdown engine with the Woebringer and Germination.
Yesterday in FNM draft I pulled a Golgari Guildmage, arguably the best, but really for one reason. My opponent would play Guardian of Vhitu Gazi, the game wasn't long but with Scattered seeds and doubling season he was on hard and fast, but I had roughly 10 mana available with two aqueducts and six lands. The guardian hit out, he had two cards in hand, which I knew were Primordial Sage and Greater Mossdog.
He played the Guardian, my turn, I played Vedalken Dismisser putting the Guardian on top of his library. Meanwhile, I drew a land played it I had a few blockers for the tokens and was at 11 so I wasn't worried about damage. Now on his turn, he played the guardian again. At his end step, I payed 5 sacrificed the Dismisser to the guildmages ability, and then returned it to my hand. Since the sacrifice is part of a cost which occurs first, the mage was already able to be targeted. And thus predicted his draw for the rest of the game while I gradually gained board control.
Do the same, sacrifice an elf to the guildmage, get tokens from germination, and play the elf again. its a little slow but the engine can easily produce enough tokens to hold off many potential threats until you can draw and play Biorhythm, Plaguewind, Woebringer, or Verdant Force.
Well thats about all I've got, notice the deck is still relatively cheap with only a handful of 2 dollar rares and a few small gems like persecute (nightmare void is a good alternative).
Just a friendly suggestion so if anyone has some critique for me, I'm always up for the challenge
