It's rare to find it but you should already have one. When you aquire a warframe you automatically recieve a card for each of it's abilities, in the case of Mag it's Pull, Shield Polarize, Bullet Attractor and Crush.

I've been told you can never sell your last copy of a warframe ability card if you have that warframe. To equip your abilities you will need to go to Arsenal then select Upgrade on the Mag tab of your Arsenal. Keep in mind your abilities like all mod cards have a cost of energy but by equiping them to the slots with  polarity you can reduce their cost by 50% rounded up. You may want to avoid equiping all your abilities until you have leveled you warframe up some to give you room for other mods.

I suggest ranking up Pull first because at rank 3 it has 300 damage over a large area which on the first few planets is more than enough to kill standard infantry. In order to make your abilities stronger you can use the Fusion option by going to Arsenal then Mods then selecting Fusion. When you select Crush you will be able to add other mods you own to it to level it up. By choosing to fuse two cards that are the same it will rank up faster than with other cards, which will save you money. Alternatively you can fuse Fusion Cores you have found into your mods. This will give you a large ammount of experiance but is relatively expencive.
