I wonder, starting with Battle of Zendikar, might it be a good idea to create OTs for each block?
* Wizards itself seems to be ramping up promotion of each block with the switch to the new system.
* There will be a greater focus on storytelling.
* As eh as it is right now, we can just point to Magic Duels as a free way to learn the game.
* We'll be sure to get more people playing the game with topics in OT.
The way I imagine it working is that we create a topic the day before the start of the first official spoiler week, and in the OP, first give a lot of information about the game itself and how to start, and then include some background info about the block. After the set is fully spoiled, activity will flow back to the community thread, then return to the OT for the next set in the block.
I'd be willing to make the OP if so.
