Seconded. And there is NO other deck with cardstock like it.
But I also like the Servants of the Light deck by Dolores Ashcroft-Nowicki immensely - it is the deck I fell in love with earliest for sheer beauty, some time in the late eighties or very early nineties.
And Luigi Scapini's Stained Glass Tarot (Vetrate? Veltrate?). He also designed the Mediaeval that has been previously mentioned here but the Stained Glass eclipses it completely. I was fully-illustrated-minors-only girl until these rich, luminous unillustrated minors came my way, and forced me to learn to read with them.
