Witchwood Grizzly doesn't damage itself. Its battlecry lowers its max HP; It can't be healed to full, but it can be silenced to raise its max to 12 again

 Actually, I never thought of minion battlecries this way. When it says "deal x damage", I always assume it speaks to the player, so I'm the one dealing the damage. Otherwise I would expect the wording to be "this deals x damage". But what you - and others in this thread as well - suggest makes a lot of sense. HS apperently always sets the minion as the default origin of the battlecry effect, the wording just isn't very clear about this fact. Too bad there isn't a rulebook where you can look such stuff up. Or is there?

 The main thing I would point to is the animation showing a small fireball, or a beam of light, or a potion, be launched from the minion with the effect. Same as Ragnaros the Firelord. It doesn't say "At the end of your turn, *this* deals 8 damage to a random enemy", it just says "deal damage", and we can see the fireball get thrown from rag to the target. Most of the game is pretty intuitive like this. I would say the most misleading card would be khadgar, and even more so when you have 2. His effect is better described as "Whenever your cards summon a minion, summon a copy"

So the marauder isn't the entity dealing the damage.

 Then who is?

The only difference between the battlecries of the marauder and, say, Fire Elemental is the recipient of the damage. Do you want reckoning not to trigger off of and kill fire elemental?
