To really appreciate the value of dumping 3 or 4 cards into your graveyard I have compiled a list of the good A cube cards that can benefit from it
Pros: Minimal effort required to snowball makes it perfect for new players still learning the game
Exquisite Design: Holographic printed anime pictures, covered with flash film on the front, protects your card and decorates your card at the same time, perfect as a card holder
I really like this one because it doesn't destroy your creatures who don't have counters yet, but gets the board open for combat
It also offers the upside of triggering whenever any creature dies, instead of just artifacts, which can be important throughout the course of the game, since we often use creatures like Weaponcraft Enthusiast and Thraben Inspector to chump block our opponent's biggest threat, and having a Zulaport Cutthroat around makes chump blocking even more beneficial
