YakovOh ok I see. This is my first set and I want to play standard. Can I make a strong deck using only this set? Or is it better to try to use some from older sets?
cc24If you want to make a strong deck for FNM, don't buy a box. You won't use most the cards, you'll only get a handful of the strong cards from this set (and likely only 1 or 2 of each), and you'll still need cards from other sets.
cc24In March/April Wizards usually release "challenge decks" which are fully-formed, Standard-Legal decks, with generally high quality/power - so definitely keep an eye out for those. There are some out now (the 2017 versions) that are mostly NOT standard-legal.
That said, if you buy the "Planeswalker decks" they are fully standard-legal, they work together nicely, and though they aren't of the highest raw power/strength, they are fun to play and you can absolutely take one to a Standard/FridayNightMagic event and have a good time :)
