Minor Fix!

So it turns out you can only use one copy of Shade Brigandine per turn. Must have missed that last line while I was reading it... all those hundreds of times. Whoops. The first bit of What Lies Within is now a bit different than it was before to account for this oversight, but it changes almost nothing as a whole.

This doesn't mean I'm fully back so early, by the way -- I just had some spare time on my hands so I was playing a bit of Legacy of the Duelist, and accidentally discovered this trying to use a pure Phantom Knights deck against an A.I.

Will try and make sure I don't make any other mishaps like that while I write the rest of it!
