Why connect decks to your collection
A deck list on its own does not tell you whether you own the cards or where they are. By allocating physical copies from your binders, Toploader OS turns a deck into a true picture of what is sleeved and what is still needed.
Allocation reserves real copies so they are not double-counted as available.
Decks display the actual printing you allocated, foil or alternate art included.
Import lists in the standard 1x Card Name (SET) 123 format.
Jump from a card straight to any deck it belongs to.
