Enjoying the card myself. I have a couple of questions however.
1) When this card is played it appears simply as a permanent, and then once the
Sandstorm is used that is when the creatures are unburrowed and then hit with 2 points of damage, correct?
2) In more semantic light, why is it that Sandstorm would remove creatures from being buried? Would it not make more sense that a Sandstorm would bury creatures as opposed to removing them from that state?
