If you want a card that prevents all and not just combat damage that way, take a look at Heart of Light.
It's worse for general use than the Betrayers of Kamigawa version, but it can still either disable the threat of an opponent's fattie, or make one of your chump blockers rather immortal.
But this one is also quite lovely. You can combine it with creatures that are useful in combat yet don't get worse from dealing no combat damage.
At first Laccoyth creatures came to my mind, but unfortunately you'll have to come up with a further card since you won't have much from an unblocked creature that deals no damage...
But as with Heart of Light, any Venom creature or those which have a usable trigger when blocking or becoming blocked will find use with this card.

The mechanics on this card can't be faulted, though there are better cards for Inviolabilitying damage to your creaturs and/or Arresting an opponents creature, this card seems to do a fair job at either.

People on Dominaria know of the sayings of Jesus? I guess that makes Jesus a Planeswalker.

@EternalLurker Ah, yes. The epic 'missed a line of text' mistake. Like when one of my friends didn't read the 'each player' part of harsh mercy
