How to Create New Templates

CONGRATULATIONS, You are already scoring highly on the test, you have put work into your template already.

This forum is fairly new. The best tutorial links I have located on the old forums can be found as follows (be aware the forum was moved here as the old hosting site was sometimes down. If the links below don't work try again in an hour or so).

Green Meep's Templating Tutorial

Part 1, Part 2, Script & Text Manipulation, Original Thread

There are also some resources that can be found in the old forum as well.

There is coding involved in this, but it is honestly not extremely complicated unless you need to do something it wasn't designed for like this.  In short MSE creates templates similar to old style HTML web pages.  There are a number of different field types; primarily choice (which can also be used to create images) and text (for entering the rules text, names, etc).  These fields are defined based upon a raster grid pattern just like is used in most image editors.  The grid pattern is also layered.  Green Meep's tutorial is relatively decent as an introductory tutorial.

The only problem I can forsee so far for you is that the image you posted is very large.  MSE has a hard-set display (it displays the image based upon your screen resolution with very few zoom options and no scroll bar for the image). To put this into perspective the MtG templates use an image size of 375 pixels by 523 pixels.  I have used a larger resolution for some of my templates but my monitor tops out at around 300 dpi (~725 pixels by 1025 pixels).  You may not need to redo the images as MSE will rescale the images to what you suggest, but your grid sizing for other fields like the text fields will need to be resized to a lower resolution.  This isn't hard but may require a paradigm shift earlier rather than later.

If you have any questions going forward or appear to hit a problem or dead end, don't be afraid to ask questions.  There are several in the forums who would be happy to help.

EDIT: Thought of something else. The other thing you will need to research is what font(s) are used on your cards.  Check with the specific game community for your cards, someone will invariably know of a close match free font that you can use, but it is game specific.
