The Two of Clubs gives the next player 4 cards from the Croupier.
This is the only card against which there is no possible defense. When someone plays it, the Croupier automatically and unconditionally sends those 4 cards to the next player.
Because its number is so small in comparison to its enormous strength, it is also called The Little Two.
On a positive note, after drawing 4 cards you will probably have something to play for a couple of rounds.
