Not sure what to do about CT because it won't actually have accurate list information. If I include all the cards people are going to think I have a weird 460 card clunker, and if I sample a list and hide cards in the sideboard I think people will only look at the main list.
You could tag cards in the main cube and the sideboard, e.g. "Variable W1 (See sideboard)". Unfortunately, CT's developer isn't part of BTP and hasn't implemented any of their ideas.
Edit: it might be worth uploading the 460-card mess as well. I know all of the cards in the spreadsheet, but the layout makes it hard to consume the full contents of the cube. CT's filtration system is also helpful to parse info. I would use the CT for a ... project ... I have in blueprint phase.
