So, the Simic deck ended up being completely unrelated to the guild it advertises. It's some kind of generic UGr deck with no simic cards in it except for a sorcery and the simic guildgate... it really let me down. I wish it would've had some evolve cards (they'd probably work well with Deadeye Navigator), and either more guildgates or a Hinterland Harbor. It even has sideboarded red spells while running a single mountain and two ways to fetch it!
While I'd like to buy some Thragtusks for my deck (I'd only need at least one since it can be fetched by Mwonvuli Beast Tracker, anyway), they're really expensive around here, so I'll have to look around for a while to find a copy that's reasonably priced.
Now I'm thinking about building the following deck:
Land (24)
3 Hinterland Harbor
10 Forest
9 Island
2 Ghost Quarter
Creatures (23)
4 Cloudfin Raptor
2 Ulvenwald Tracker
4 Strangleroot Geist
3 Zameck Guildmage
1 Wolfir Avenger
2 Borderland Ranger
1 Dungeon Geists
2 Deadbridge Goliath
3 Wolfir Silverheart
1 Strumgeist
Spells (13)
1 Rancor
1 Cyclonic Rift
3 Tracker's Instincts
3 Spell Rupture/Dissipate
2 Garruk Relentless
1 Ooze Flux
2 Syncopate
Sideboard
2 Pithing Needle
3 Young Wolf
1 Deathrite Shaman
3 Mayor of Avabruck
1 Nightshade Peddler
3 Stormbound Geist
2 AEtherize
The deck's made with cards I own (except for the AEtherize and a pair of Zameck Guildmages), and came to be when I noticed the synergy between the new Simic Guildmage and Undying.
If I have the chance, I intend to add a pair of Vorapedes (to stay on-budget), Breeding Pools (if I manage to trade my surplus shocklands for them) and perhaps some Simic Charms; I'm also considering Yeva, Nature's Herald, although I'm not sure what I'd take out for her.
The sideboard is a bit strange since I'm not sure what I should add. The Undying critters are meant to slow aggro down while further enabling Zameck Guildmage shenanigans, while the Mayors are meant to punish slower decks while pumping some of my creatures.
Any suggestions?
