One of the greatest games I've ever seen...
It's 2011 or so, and Mike Egan, on U/W Landstill, is playing Visna Harris, on some form of Grixis Control. We're at a fairly developed board state, Visna has some number of Underground Sea and Volcanic Island in play, Egan has a Mishra's Factory and some number of Tundras/basics.
Egan taps and casts Standstill. Visna cheers. Literally cheers.
Egan, confused, asks if it resolves. It does. At this point in the game, all Egan has seen is typical blue stuff. Fetches, duals, Force of Will/Mana Drain, etc. Nothing is out of the ordinary. But this is Visna Harris.
Visna untaps, and plays Bazaar of Baghdad for his turn. Is he on Dragon? Nope. He taps the Bazaar, draws two, and pitches THREE BLOODGHASTS, then passes.
What the hell is going on here?
Egan untaps, activates the Factory, and swings for two, then passes.
Visna untaps, plays MISHRA'S FACTORY to recur his three Bloodghasts.
The game becomes an utter blowout. Egan pops his Standstill to try and handle the Bloodghast/Factory army from the Grixis Control deck, but it's too much, too quickly.
There are other good stories, but that one's great.
