my friend plays a super irritating deck that's basically delvers, 4 copies of some other horrible creature, and the rest is all counters and bounce. i managed to get a mill off on my first turn that hit one copy of each of his creatures, which i then proceeded to surgically extract.
normally as soon as he has three lands up, you might as well give up because even if you win you'll have to fight through 30 minutes of bullshit counters to get there that it doesn't even feel worth it.
that game was glorious though. it was over before he even got a turn and he knew it, but i refused to let him concede and made him play it out.
