Just use the BW GIMP guide, delete the text box with the Weight and stuff in it as well as the flavour text (description), and replace the blank with a Full-Art one. Afterward, use this short tutorial to add strokes to your text/symbols:
1. After you've typed all the text for your card and checked for errors and all of your symbols placed, hide everything but the text and symbols.
2. Go to Image > Merge Visible Layers and accept the default settings.
3. Create a new transparent layer and drag it below the merged text and symbols layer.
4. Go to Image > Merge Visible Layers and choose "Clipped to bottom layer."
5. Duplicate the layer and show all other layers.
6. With the lowest text/symbols layer selected, go to Colors > Colorize. Drag the Lightness slider to 0 and click OK.
7. Go to Layers > Transparency > Remove Alpha Channel.
8. Go to Filters > Distorts > Value Propagate. Select "more black" and click OK.
9. Go to Layers > Transparency > Color to Alpha. Choose white and click OK.
10. Go to Colors > Invert. If the strokes are too fuzzy, duplicate the layer.
That's it. There may be other ways, but this was the easiest for me. It might seem like a lot of work, but it's really quick (though not as quick as Photoshop, which you can just apply a stroke to text as a Layer Style). I actually still prefer this technique over Photoshop's stroked text. It turns out a lot crisper and the text is easier to read. I used Photoshop to stroke the text on my Mewtwo FA, which I regret doing.
