I'm not sure how old this thread is, but stumbled across it...
I find understanding when people feel that TnRs aren't super easy most of the time, but I don't agree with the impracticality statement.
Most TnR's use some extra card, that's it...I admit, the torn too gimmick is a bit daunting to have on top of your deck, but looking at other TnRs they're pretty do-able.
Look at reinCARDnation, that's impromptu, to me it doesn't have the visual appeal of some others, but it uses just one card and angle wise isn't too bad at all, but some people might worry about pulling it off.
That kind of a thing isn't impracticality, that's just not feeling the effect, I know that millions of people use thread all the time.. I major in PK stuff, but I don't use thread AT ALL in my shows. I don't like to be hooked up, but that's not to say it's impractical in the least as it's been proven otherwise!
so to conclude, you should say such bold statements as just because you don't get along with something, doesn't mean it won't work perfectly for someone else - comments about impracticality can stop people from picking something up that could be great FOR THEM.
So there's my little thoughts on the subject!
