Meta?

[Neotenens]

So, after abandoning the TCG for three years to play Yugioh (which I still play), I decided to try the TCG again. Problem is, I have no idea what's good right now. I don't have any fairies or dragons, because I quit before they got an energy, but I have a single EX (greninja). So I was just wondering; what's met right now? I don't intend to become a master, I just play a deck I like (Mostly grass and psychic, couple waters, lots of free retreat like accelgor and dustox)
