I have an interaction that seems wrong:

Phyrexian vindicator and Ochran assassin are on table, and i play Ascent of the worthy, targeting the Phyrexian vindicator, so any damage dealt to my creatures is redirected to phyrexian vindicator.

The issue is, when ochran assassin forces all creature my opponent have to block, Phyrexian vindicator will register the total amount of damage dealt to Ocran assassin, for each block.

Exemple: *Opponent have Creature 1 (5/5), Creature 2 (2/2), Creature 3 (3/3)
*Ochran assassin attacks, forcing creature 1,2,3 to block for a total power of 10.
*Ascent of the worthy will redirect all the damage to Phyrexian vindicator, which will deal 10 damage, 3 times. Instead of 10 damage on one instance.

[Phyrexian vindicator]
If damage would be dealt to Phyrexian Vindicator, prevent that damage. When damage is prevented this way, Phyrexian Vindicator deals that much damage to any other target.
[Ochran Assassin]
All creatures able to block Ochran Assassin do so.
[Ascent of the Worthy]
Choose a creature you control. Until your next turn, all damage that would be dealt to creatures you control is dealt to that creature instead.
