The fact it triggers on being blocked puts your opponent in a loose loose situation. Also if the blocking creature is equpped or enchanted you can desdestroy the buffer before damage is assigned.
Considering how many playable enchantments and equipment there are, this will be unblockable a descent amount of time. Very nice card.
This.
I like the art.

Admittedly it stops being unblockable on the last swing, since most opponents would rather lose their best artifact or enchantment than the game. Still, if you've been swinging that much, the damage is probably already done. Very good Limited card, though highly unlikely to make the Constructed jump.
