Hello. As you can see this is my 1st post. I never really made my own deck when playing this game, but I'd like to start. I know majority of the basics and such, and still learning as we speak. The last time I played this game a friend of mine let me use his TNT deck, and I liked it very much. (That was about a year or 2 ago)

So I'm wondering if TNT decks are still playable. If not, are there any decks similar to it that can be competitive? And how would one go about building their own deck? (can I get a sample if possible) Thanks in advance.
