MTG has an official youtbe channel, and there's some pretty helpful turorials on there.

It may seem pretty simplistic and obvious what they're teaching, but they helped me out a lot.

I saw those on the magic website. I need to go over it still. And just checked Steam does not have any Magic games for Mac.

If you were to build a deck from scratch, what color/s would you go for? Also, any ideas on what sort of direction you'd like it to go?

None right now. I just finished cataloguing all of my cards. And putting them in a binder so i didn't have them flying everywhere in my room. And the idea for the colors is green white blue. i think....

My card collection is pretty much just sitting on my floor in piles of colour. I make so many different decks that it's inconvenient for me to have them stored in any way. Just quick access to anything i need on the floor <3

If you're just starting I would recommend going for a mono coloured deck as your first venture into deck building, and then once you've had a bit of time to get use to it you can introduce a second colour, or a third if you're that confident.
I personally have yet to get to the point where i feel like i could pull off making a 3 coloured deck. that's with 2-3 months of regular play Dx

Its just that I feel like mono colored decks can get to be really cheap and frustrating for whoever i am playing with.

I wouldn't say that's true at all. there's absolutely nothing wrong with mono coloured from what I've seen. Plenty of the people I play against have been into magic for years and still run some mono-coloured decks.
the main issue i see with mono coloured is that it can a weakness sometimes.
say you had an all black, and they had creatures with protection from black. you're screwed.

I personally run a black/blue, blue and green.

Mono-colored is best for newbies, no offense. They're easier to work with.

Hell, except for my sliver deck, I do not go beyond two colors. And I've been playing for over 10 years.

But remember, mono-color doesn't limit you really. You can still have artifacts which many do not require a certain type of mana. Any will do. Also, with multi-colored decks, you might have mana problems-not having enough or not being able to get the color you need.

Ok thanks for the input guys.

yeah, the hardest part of building a deck for me is making sure I have the correct balance of mana. Being mana starved, or the exact opposite can be a real issue. and the balance becomes harder and harder to sort out when adding extra colours.

That makes sense. And you just asked what kind of deck i was wanting to build in the future. Right now I'm just sticking with a green infect deck that i got. I'm gonna be slowly trying to build off of that one for now.

If you're worried about being a pain to other players.. infect is a bad way to go :P It annoys a whole lot of people. We even have a rule where infect based decks aren't allowed when we play >_<

That's my point. That's the only monocolored deck that i have. Which is why i've been trying to figure out how to build a different deck. I love the infect deck, but the people i play with hate it, because it is really cheap, which is why i've been trying to figure something else out.

infect is annoying and cheap, but that doesn't reflect on mono-coloured as a whole. It's very possible to make complex and fun decks with the one colour. It's also easily possible to make decks that can win.

I made a dual coloured infect deck once, but it even annoyed me >_<

I only have enough cards to make a green monocolored deck and most of my cards are infect and at the moment i dont have the money to get more.

I have a mono red deck that can do 20 damage in one turn /swag XD
