Send 1 Level 4 or lower Normal Monster from your Deck to the Graveyard, and if you do, add 1 monster with the same name as that card from your Deck to your hand. You can only activate 1 "Painful Decision" per turn.
Couple that with Wall of Disruption and Forbidden Chalice for protection. Just realize this box is basically the same as Dawn Of Destiny. That is a lots of Meta card to build a deck in just one pack. Only this time it's the long forgotten Harpies
