I personally hate to play with stage2s...
No kidding, most of the deck I enjoy playing the most are either all-basic or basic/stage1s. I prefer the tactical side over the downright damaging side of play with low-energy high-damage high-HP Pokémon, which is probably why every deck I make is full of techs, or can usually be considered as a whole bunch of techs thrown together. This is probably one of the reasons why I liked AMU (although I usually try not to play archetypes as much, yet it's safe to say that my AMU was so very unlike the regular AMU archetype).
I also like a more defensive and safe kind of play, I guess this explains my love for mynx (which I played one year after it was invented, meaning it was pretty much a completely different deck, but an awesome deck nonetheless. General concept of Mynx is Mew ex + Jynx + a bunch of wobbus for this who didn't know). I also love to control the field, which can be categorized with defensive play.
I hated last year because it pretty much forced me to play stage2s (which is when I start playing the weirdest decks ever, like magnezone (swarming the DP one, plus the old bronzong, it actually worked pretty well), porygon-Z and Butterfree (no kidding, ask anyone who saw me at worlds)).
So yeah, I have a pretty weird playstyle, which gives me a pretty cool advantage towards people who are unprepared for this kind of stuff.
