For songs in A minor- drop the B string to A. Some folks also will drop the bass E to D but this is not necessary. Also EADGAD works as an open tuning. You can play the bottom E and A in a standard fashion up and down the neck. In this tuning you can play out of A minor (with a little more work on the 1st E) or play out of D.This all works with a pick for me as I do not use finger style.
