Colour or black & white
Both work. The layout uses black text on white with no background fills, so
greyscale loses nothing but the card art. Choose whichever your print dialog
offers — if you're printing a want-list to scribble on, mono is cheaper and
just as readable.
Standard letter paper
Sized for 8.5″×11″ with 0.35″ margins, so it prints from any
home printer without scaling or "fit to page" tricks. Nine cards land on
every sheet, every time.
Sized to read, not to swap
Cards print at 2.2″×3.08″ — about 88% of a real card. Full-size cards
plus a price caption don't fit three rows on a page, and a page with two rows
wastes your paper. These are reference sheets to read alongside your binder,
not cut-outs to fill empty pockets.
Prices you can trust
Every price is the ungraded near-mint market value — TCGplayer where it's
available, PriceCharting as a fallback. Never a graded price dressed up as a
raw one, and never a guess: a card with no reliable price shows none at all.
