The Dragons of Tarkir league has gotten underway! It's going to work just like the last one. That means that you start your pool with a Dragons Pre-Release box. After that, you may add two drafts each month to your pool (or open 3 packs in front of Jackson or another league player if you can't/don't draft), there is infinite in-league training (with no external incentives), minimum deck size of 60, as many copies of a card as you want in a deck. We'll still be playing for fun whenever you feel like it (Jackson has a great deck this time around).
This is the magic league that we run. Players have a pool of cards to build a deck from that gradually grows as the league goes on. For more details, visit our magic league page.
