Maraudeur creux

Hollow Marauder’s first ability doesn’t change its mana value, which is always 7.

When Hollow Marauder’s triggered ability resolves, the next target opponent in turn order (or, if it’s a target opponent’s turn, that opponent) chooses a card in hand without revealing it, then each other target opponent in turn order (if any) does the same. All chosen cards are then discarded at the same time.
