Chump blocker

A chump blocker is a (generally small) creature assigned to block a larger attacker, which will ultimately die at end of combat and the blocking is solely done to prevent the damage that would be dealt if the creature was unblocked. Chump blocking occurs most often by players who are losing and trying to gain additional turns in which to draw answers, or alternatively by players with some method of generating large quantities of chump blockers to indefinitely stall an attack. This sort of blocker is most commonly a creature token.

Trivia
"Chump-Blocking Orphan" is the name one of the "cards that did not make it" in the Unhinged hidden message from the words at the bottom of the cards.
