Officiele rulings

2/9/2017
You divide the damage among the target creatures as you cast Monstrous Onslaught. Each target must be assigned at least 1 damage.

2/9/2017
The value of X is determined at the time you divide damage. It won’t change later, even if the highest power among creatures you control changes.

2/9/2017
If some (but not all) of the targets become illegal, the original division of damage still applies, but no damage is dealt to illegal targets. If all targets become illegal, Monstrous Onslaught won’t resolve.

2/9/2017
The damage is dealt by Monstrous Onslaught, not by the creature with the greatest power among creatures you control.
