Hi
@Elshubi
I've collected and played magic for many years. In my time playing I've normally found about 1-5% of current friends actually do have / play with these cards just so few people know of it they don't exactly ask so I would start there if I was you. Always nicer playing with friends although teaching friends can be difficult*
If no friends play MTG then I'd suggest you download the online game to pc or cellphone and try get used to it there and see if it's something you can enjoy. I think the latest game was free to play and you could unlock more decks by playing / earning in game currency etc (Can spend real money but I wouldn't, real money is for real cards in my mind atleast).
If you come to find that you do enjoy the game and happy to go further then normally your small comic book, games store sells MTG cards. Hopefully they are also doing Friday night magic comps, there should be some way to find out where your nearest comp is. (Once you have a "current" deck, start attending these and mingling to learn new things and get tips etc)
From there as time goes by you'll gradually buy more cards and starting mixing it up even more.
To start I'd suggest you buy a box of 2 duel decks. This gives you two decks that are built to be played against each other so straight of the bat you've got two working decks. Also lets you start playing with friend / family / random strangers even if they don't have their own cards.
MTG sells cards in all formats, booster packs, booster boxes, pre-made decks, duel decks, Commander decks (slight variation from regular game).
So there's many doors of entry into mtg, every year they release a new set and theres a few releases as part of that set. When it comes to comp's they normally only allow the latest set + the last 2 years so if you wanna compete at tournaments don't buy old* decks as the type 2 comps are much less common.
Google what is the latest edition to be released and look at the pre-made decks there. Might find something that appeals to you. Alternatively look for specials on websites and get 1 or 2 decks and some additional cards to modify.
This got really long really quickly so going to cut it off here. If I've missed anything feel free to ask.
Stores I know of that sell:
BT games
Raru.co.za (decent specials on decks occasionally so would look here infrequently)
It's created by "Wizards of the coast" so there might be a way to see who all they import to, to find your local supplier / cheaper deals.
