This deck tries to give people Sorrow's Path, then tap and untap it a bunch of times.
Most of the cards do one (or more) of these things:
1. Tutor Sorrow's Path;
2. Donate Sorrow's Path;
3. Tap/untap lands
I am still doing some tuning this deck so it gets better; but it's good enough for now. For example, I'm probably going to add Praetor's Counsel.
