The humor is in the game this card is referencing: Craps
Battles begin the game in your deck and can be cast as a spell during their controller's main phase when the stack is empty
It is easy to play around Force Spike or Daze but does really hurt your early game tempo to do so
You can do the math and see what happens if every player draws 7 cards after a wheel effect
First off, it has flash, so you can drop it at just the right moment and immediately shrink a creature by -4/-4, potentially taking out a key threat
Play your cards right, and when your instant and sorcery spells head to the graveyard, they won't stay there for long , as there are creature abilities in play that can get them back in your hand for another round, much to the dismay of the other players around your table
