Gravepurge
1/22/2011 You can cast Gravepurge with zero targets. If you do, you’ll draw a card as the spell resolves.
however take into consideration:
2/25/2015 You can cast Gravepurge with no targets. If you do, you’ll just draw a card. However, if you cast it with at least one target and all of those targets become illegal, the spell won’t resolve and you won’t draw a card.

Are any other cards possibly affected by this bug?
