I would say that I am a pretty safe player. It took me a while to figure this out, but if it is possible for a good opponent to do something, they are going to do it. I try to think of all of the possiblities, for instance, figuring out how many cards would they need to get something out of their active, evolve, and attach an energy or something along those lines. I sometimes take risks, but I try to run at least a couple numbers in my head, but a lot of the times I make risky decisions.
For instance if I have a chance at a donk, on lets say a coin flip, and if I go that donk, I will have a cruddy set up the rest of the game, I am probably going to be going for the donk.
As for the speed/lock aspect of the game, I usually like Speed decks, but I can appreciate interesting locks, for instance, my old
Rapidash lock, or something like FlyLock from a couple formats ago. For the most part I go straight for the throat with speed decks. Last format, almost every deck that I built was a speed stage 2 deck, 3 BTS, 4 Pokédrawer + and that jazz. This format I have been looking into Eel Zone and ZPST, simply because it is something that I can make a speedy list of. I tried playing google's, but was simply irritated that I couldn't get a T2 set up with it, so I stopped trying.
The other thing that I do a lot, and would almost say I specialize in, would be unexpected techs. I love playing a copy paste meta deck, and right when people think they know every card in my deck, I pull out some weird counter like Unown CURE or something. For instance, last year at State Championships, I was playing a Gyarados list, but I was playing 4 Night Teleporter, 2 Azelf and 4 Special Darks (this eventually became the norm, but whatever). I would do things like pretend that a Magikarp was prized, just to draw out an SP player's Power Spray, so that I could try to get an Uxie with Night Teleporter. It actually worked pretty well, I ended up taking third place at the tourney, probably would have gone farther if I would have been paired against one of the two DialgaChomps in top as opposed to the only LuxChomp. I like how quickly this turned into a rant, I miss the past
