No No No Sheep
That is exactly what I meant.
Each copy of Protector of Lorien is limited to 3 cards per phase.
That means, if you have three of them in play (regardless of whether they are on the same or different heroes), you can discard up to 9 cards each phase (3 for each Protector of Lorien).
who got the luxury of discarding 9 cards at 1 round ???
