This will likely be my last Cube for this go-around. I first-picked Swords to Plowshares, second-picked Griselbrand, then third-picked Monastery Mentor and decided I would build around it. The end result was this RW pile:
The Armageddons did
work round one against a UB control deck. The games weren't even really close, although I had to play pretty deliberately to keep tempo and pressure his mana enough to deploy the haymakers.
Round two I faced a GR Ramp deck, and got to curve Firefist Striker into Mentor in both games. Game one I beat down my opponent's T3 Xenagos by playing a T4 Wargear and attacking past the Satyr token, and my opponent never caught back up. Game two my opponent played T3 Purphoros, T4 Siege-Gang Commander (doming me for 8!) but my T4 Helix into Dragon Fodder meant I could attack past the three tokens while making a giant board of my own. He Flame Slashed the Mentor and played out a couple of duders, but T5 I played Ajani Goldmane into my board of 5 creatures, 2 of which had prowess. My opponent commented on how "unreal" my deck was (he was actually quite nice and didn't really seem salty) and then scooped.
Round three I played a pseudo-mirror - a mono-white weenie deck. Game one things just worked out perfectly for me, with my threats lining up against what he was trying to just well enough to win the race behind a Hellrider and an Ajani, with Thundermaw Hellkite doing work against a Baneslayer Angel to push the last bit of damage through. I sided out the Wire and one of the Geddons, bringing in Pillar of Flame and Gore-House Chainwalker to lower my curve. I got daggered by a Mana Tithe on my Mentor in the second game, lost a board of tokens to a Parallax Wave, and never really had a chance. I sided out Firefist Striker for Phyrexian Revoker - faltering one blocker against him probably isn't going to do it, and naming Wave against him gives me outs. Game three I had to mulligan to five, but I drew perfectly, curving Porcelain Legionnaire into Blade Splicer, then backing it up with Journey, Swords, and Path. The critical moment of the game was when he played Leonin Relic-Warder to pick up my Journey, putting an Exalted Angel back on the table, followed by me topdecking Pillar of Flame to remove the Relic-Warder and the Exalted Angel again. I played around Mana Tithe religiously, and was rewarded with a 3-0.
