The check
Every format's rules, applied as you build.
Deck size, copies, Leaders and Bases, Extra Decks, colours and inks, ban and limited lists — each issue says exactly what's wrong.

Card by card
Each line at today's fair value, with the deck's total.
The gap
What's missing
Cards you hold in your binders count; the rest is the cost to finish.
Honest matching
No guessing
A line we can't match stays unmatched — never a guessed printing.
