Can anyone give me a quick summary of the metagame and how the different teir 1 decks work?

Back for the holidays and I've been loaned a deck (RDW) for FNM. I used to play magic (back during ravnica) but I stopped after university picked up. Lately my friends have been getting back into it, but I'm not super comfortable with the metagame and understanding my opponent's decks. So far I've only been able to get a few licks of practice in against Kessig Wolfrun, Tempered Steel, and Birthing Pod. Could anyone give me a quick rundown of the other types of decks, how to recognize them early, and what I should be prepared for so I don't get totally stomped at FNM?

For example:

Tempered steel: Very artifact heavy, often relies on metalcraft. Very powerful Aggro deck, doesn't run planeswalkers, relies on tempered steel to buff their guys heavily. Key play is to try and outrace it with RDW before tempered steel comes out, or play a more control heavy game after the sideboard and burn the creatures out before tempered steel comes into play.

Note: My deck is missing certain cards (only 1 pheonix, 1 koth, 1 hero, 2 stormkirk noble, 1 gutshot), unfortunately.
