Here are the steps to form the plan (as I develop it, each step will get its own set of posts):
1. Catalog what I have.
2. Set up a sequence by which I will pick a small number of cards and make a deck with them.
3. Track cards that I have already played using a coverage metric.
This is a big fun task, as I now have 5,624 distinct cards by name, and a total of 17,483 cards.
3. The cards I have played with a lot are off the list for now. Some are staples that need to go in almost every deck of a type. How could you not play Ponder or Path to Exile if you can, right? They will be in the decks, but only because I need a reasonably working deck that does not lose every single game-that's no fun.
Here are the counts of the heavy play cards. I came across a total of 609, or 10.8 percent of all of the cards I have by name.
When I look at the rarities, excluding four promos and the three Moxen, here are the counts by set. The counts are about equal for common, uncommon, and rare.
April 14 update: OK, I lasted two weeks, time to buy some cardz!
