UG Polyphant Massacre

explaining the sideboard to myself lol against big red aggro red, side in spell pierce and fog, the fog will allow you to last long enough to combo off, and spell pierce makes them cry when they attempt to do a turn 3 koth or even a turn 4 koth, while only tying up 1 island. against splinter-twin you sideboard in spell pierce and unsummon. the key to stopping that deck long enough is just countering the exarch and splinter twin interaction. aggainst caw blade and variants not much is needed to bring into the main deck from sb. you could bring in spell pierce, considering battle skull comes out on turn 3 or 4, you could use a naturalize to break it before they have the mana base to make it invincible. rw midrange mid range is not really a problem unless theyre running any of the heroes from mbs, that turns a mid range deck into a turn 4 win or turn 5 win by just slaughter, i would suggest unsummon and spell pierce. eldrazi green red well, um.... i would think that countering any of the eldrazi would ruin their day or countering their awakening zone. one thing to watch is that eldrazi should now be running fresh meat as a contingency plan. soul sisters unsummon and spell pierce, pronto! if they have a relic warder and just cast their phyrexian metamorph, unsummon the @#$% out of the warder, or spell pierce that metamorph.
