The worst kinds of decks are mill and sliver/ally/etc. They're so annoying to play against. With that being said, I have an elf deck with a record of four turns, generally around 7 though. I also have a rainbow deck that is awesome to play with full of over powered cards and this land hate deck, which isn't great, but is fun to play with. I have never played in FNM, nor do I keep up with standard. I play strictly for fun. With that being said, I have recently been interested in going to an FNM, but I don't know what the time commitment would be like, and I'm not that great at making decks, especially quickly, which I feel like you would have to do at FNM.
That land hate deck looks really fun to play. You don't have to keep up with standard to play at FNM. A lot of game stores have Modern or Legacy tournaments on Fridays as well. It's normally around 5 bucks ( if they are doing prizes) or free to play. The time commitment would be around 3 hours. Sometimes I get out of there sooner. I would check it out. A lot of the players are really kind, and some will even evaluate your deck and give you cards to fill it out.
