Draft effects collection

You don't need to sell premade sets of cards.

A way to create a leveled random list of cards can be developed easily.
A National Coordinator can pick up such a list and order the cards online.
Than he can separate them by smaller sets and use them for draft tournaments where people give all the cards back in the end.
For the next tournament, new mini sets are created.

The Swedes already do this with 3rd Edition boosters.
