Played on an online magic-league tourney yesterday. It's single elimination and I was paired against Hive Mind game 1. You can check my opponent's list at

Turnabout
Game 1 he casts Show and Tell turn 3. I opt in response and find an Island (which I cheat into play with his Show and Tell). He drops Emrakul. My turn 4 I opt looking for a High Tide but got an Island instead. I drop it and pass the turn. I try to go out on the begin attack phase without a High Tide in hand. With 4 untapped lands, I tap everything and cast a Reset. He Intuitions for Force. I Twincast the Reset, untap, dig a little bit longer, and fizzle.
Game 2 he drops a Leyline of Sanctity turn 1. After some digging on our parts, he casts Show and Tell turn 4. I don't have a counter and cheat an Island into play instead. Emrakul hits the table on his side. I try to go out next turn. I resolve a High Tide on his upkeep. When I try comboing off he Intuitions for a Pact of Negation and tries to counter the Meditate. I cast Flash of Insight, some Resets, Wish, and cast Blue Zenith drawing 11 cards. I leave 4 mana open to untap but didn't get one in the 11 cards (I had cast 3 Resets already). I fizzle after some more desperate attempts of finding an untapper.
In general, I had the impression that I never came
even close to winning. Keep in mind that he has 3 Emrakuls main deck, so I would need a pretty successful combo to Brain Freeze/Remand/Trap/Zenith him. Game two he even dropped a friggin' white Leyline in play. They play somewhere around 12 hard counters (4 Forces, Pact of Negations, and Intuitions). I don't know if those people who said Hive Mind is an OK matchup playtested more, but my impression is it's pretty tough.
I think I'll bleed for some Forces. That will certainly help.
EDIT:
Was browing Legacy daily results and found this Solidarity list 3-1 (search for Th00mor):
