Powers as "trading" card

[Madeiner]

Hi there. I am designing an homebrew spell system to be added on top of the existing d&d system.

I have decided to use a trading card style format for ease of use, since powers are mostly straightforward.
I have tried making some with: http://www.mtgcardmaker.com/
However i find the image is too big for all the text to fit, but also it is missing crucial icons; i need a few more than those.

Can you recommend me another creator that allows for what i ask?
I wouldnt want to just make a pdf as it's just easier for me to use some premade creator.

I'd use Magic Set Editor instead, and download an appropriate template for the size of whatever you're doing.
