I have only been playing Magic for about two months, and recently started deckbuilding. I have built an Orzhov and a Dimir deck, which I have posted on this site. Anyone who is more experienced at this, comments and advice would be really helpful! :D If you suggest a change to one of my decks, please tell me why you would make this change, as well, so that I can learn. Thank you!

The decks you're playing are okay starter decks for having fun. I would try to find what works and just acquire more copies. running 4 of a card makes it many times more likely to show up when you need it. Try to stick to 60 cards. A little more than a third of your deck should be land. 22-26 depending.

As a new player when you trade get an app (Iphone and Android have decent apps) or a price list. Everyone trades based on value of individual cards. Don't let your self get taken advantage of. If you have a 20 dollar card don't trade down too much. Trade for another $20 card or 2 $10 cards. Don't trade for 20x$1 cards. That's very much not in your favor.

There are tons of resources out there to look at.

• Gatheringmagic.com has articles on a lot of topics. Standard, modern, casual, fun.
  SCG (star city games) also features articles about decks strategies and play.
  Look on Twitch and Youtube for videos and streams about playing and deck building strategies.
