Games with no + actions, no trashing, Travelers, Mill (only cantrip), Enoy, Sulk, Gollum on the board.
I buy up 7 of 8 Mills (including discipling one), and via their deck cycling run through the travelers really fast, get my teacher. Buy a couple of envoys waiting for the teacher to come through the shuffle, knowing I'll have a pretty unbreakable Mill/Envoy engine as soon as I get +actions on the Mill. Opponent meanwhile has gone for a couple of Sulk's for economy, then is going for a Gollum type engine (which is some turns off firing), and is some way behind on getting his teacher. Game pretty much in the bag unless I really mess up, or so I thought.
Then this happens... opponent plays one of the Sulks. Hits Locusts (1 in 12 chance). Hits the teacher (1 card in a deck of about 20). To say I was irritated didn't do the situation justice... to add insult to injury, my opponent finally gets his teacher just before a shuffle, and of course it's in the next hand he draws
I think I lost by about 20 points...
