Then buy a deck builder set like this one!
Perfect to get a taste and then post it to expand perfectly with booster and or Intro Packs. Must not the beginning but his, you can start right away:
In addition to 125 more or less random cards (also a few good spells it!) And 100 Standart countries (the "currency" of Magic. Necessary!) Are also 4 booster packs contain 15 cards each, which alone about 12-16 Euro would cost.
Since it can happen that you have the same one or another rare (rare) or Mythic Rare (very rare) case.
Top per person 1 order such a set, then you have the same a nice, reasonably flexible arsenal of cards and can replace the first card. And if possible - but it must be ned - a 20-page per player cubes also order;)
From me the thing gets a clear recommendation. But be careful! Magic can be addictive and go discreetly into money!
