All I want to know is ...
Just what decks is the OP using that is flunking against Highlander decks?
And long games, hell I welcome that. Sure, there's King Phaoris BS, Conjurer's Calling and the occasional out of control Shudderwock play or Inner Fire crap, but a much better game than any Silver Hand Paladin of last year, murloc shaman or druid tree garbage of today.
I just beat Quest Paladin with Big Paladin, and it was the grindiest game I've been in a LONG TIME. Apparently getting six full health Damaged Stegodons via Vargoth+Kangor's Endless Army shenanigans (there was a rez secret that spawned a third Stego) was the play of the game, ruining his mummy farm, but then I had to cope with him sticking every taunt, reborn and egg counter coming off his top deck. I easily could've lost if I played the wrong spell or didn't take a risk with a sword hit; at one point I had 4 health. One stegodon made it to the end.
As for Highlander, I've played once with mage, and didn't even get to play my singleton legendaries. Made a Zoo Warlock rage quit when he got suckered into playing everything into a blizzard +2 spell damage play and giving me an 8/4 sea giant to add to the casualty list when he lackey rushed into a minion of mine moments before. Who needs Reno or Zephrys to win in Highlander when you got aggro decks and the idiots who play them?
