Unleash is a keyword ability.
Details[]
Unleash was the guild mechanic for the 
Rakdos guild in the Return to Ravnica block, which went on a total of 13 cards.
When you play a creature with Unleash you may put a +1/+1 Counter on it and it can't block while it has a +1/+1 counter on it.
By putting the +1/+1 counter on the creature, you get an overstatted creature that can't block, and by not putting the +1/+1 counter on, you get an understatted creature that can block for you in a pinch.
It allows an aggro deck to block to prevent itself from being overwhelmed.
It should be noted that putting any +1/+1 counters on your Unleash creatures, will trigger the Unleash effect.
