I like this style and I want tutorials to learn how to do something like this what should i type????
Terms that might describe it:
- line art
But it doesn't have a particular name. In 20 years it might be called '2010s style'. :)
They are fairly easy to create (at least in terms of mechanically). Basic tutorials for any vector illustration art should get you headed in the right direction.
I don't think there is a "style" to name.
These are just simple icons, made from a combination of lines, shapes, strokes and fills. Just basic Illustrator stuff, and nothing complex. The bottom parts of the cards have some gradient fills.
If you are want tutorials then you probably need to search for beginner tutorials that cover using the Pen Tool, the Polygon Tool, the Rectangle and Ellipse tools, and tutorials that cover applying strokes and fills, and gradient fills.
