I hadn't considered the plant token land as I tend to like to use my mana the turn it comes in.
Well I top 8'd at game day. Saw control, control, control and some more control. Early on, I lost to a good friend who was running straight red goblin/burn. Game one was close, but he managed to keep top decking lands after 9 had been destroyed (1 destructive force, 3 acidic slimes and an artisan for a return of an acidic slime). Game two had me win at 1 life (he was at 20) in a series of dramatic castings. Last game was a complete 'God draw' by him with me eliminating as fast as I could and him beating me down to 9 by the end of his turn 4. With the field cleared of goblins and him with 3 cards in hand (tapped out) and 3 mountains in play, he responds with a "I'm sorry" revealing the 3 lightning bolts in his hand. Starting off 0-1, I went on to win out to make top 8.Friday saw me add one swamp, 4 tri-color lands and 3 maelstrom pulse to the deck. It was a good call, with the Pulses always killing planeswalkers, but I think I could have easily gone with pithing needle and thereby protecting my mana base. The screwy land base did cost me game one in the top 8, going out to two tectonic edge's at once. For gameday, four of us went. And all four of us made top 8. Then immediately we all lost. Vampires, Green-Eldrazi, Mill and a version of RDW. I lost to green-red-control. Instead of Eldrazi, he ran counter spells. Everyone else lost to UW control (which I beat 3 times in swiss). After playing the Green-Eldrazi, I found myself very happy with it. path to exile hurts a lot, but oblivion ring is much weaker. I also found myself liking several things and wishing on a couple of other. First, spellbreaker behemoth deserves a spot in the deck. At 1RGG he is a great meta-call in my area and easy substitute for obstinant baloth. His ability to protect against mana leak and other counter spells is awesome. White Blue control has answers like nobody's business, but the behemoth forces the O-Ring or Path to deal with his threat. Second, 2 destructive force is enough. Third, all is dust is a great card, often netting you a creature return to boot. Fourth, the proper compliment of Eldrazi appears to be 5 with a possibility of a 6th depending on your sideboard. Those 5 are: artisan of kozilek, Kozilek, Butcher of Truth, Ulamog, the Infinite Gyre, it that betrays and emrakul, the aeons torn. Coming in at a possible 6th is spawnsire of ulamog depending on your sideboard. Acidic Slime provides a big boost for anti-control (take out man-lands) and also kills sideboard cards of all types. If I could run 8 of these guys I would. Given the mana ramp, mold shambler seems like a good card to consider. Given his ability to take out Planewalkers, land, enchantments and artifact if you get it kicked to 6 mana total. We'll that was my take on Gameday while running a version of Green-Eldrazi.
Eldrazi are fine, but they are really costly. There is a turn three win with Primeval Titan:1. Forest, Llanowar Elves.2. Lotus Cobra, Mountain, Add G mana with Lotus Cobra, Llanowar Elves, Amulet of Vigour.3. Misty Rainforest, Add G mana with Lotus Cobra, Sac the Rainforest for a Forest, Add another G mana with the Cobra, Play Primeval Titan, search for two Teetering Peaks and target the Titan with both of them, Add any colour mana with the Cobra, play a Goblin Bushwhacker kicked, attack with everything that is untapped, search your library for another 2 Teetering Peaks, again targeting the Titan.Turn 3 WIN.
