I have no idea how this even works

So this is by far the jankiest deck I've ever built - but it works. Most of the time. If you get a bad draw and don't have all the pieces you need to start cycling things back and forth from the void to the top of your deck, or if you don't have a clear way to get in some chump blockers by around round 3 or 4 at the very latest, you will fall apart like wet toilet paper to even the most modest aggro deck - this is a slow deck. But I've found that quite consistently, if you can stabilize the board and maintain decent card advantage all the way through to turn 5 or so, you should be fine.
