Rogue Trader — Whenever Neyam Shai Murad deals combat damage to a player, you may have that player return target permanent card from their graveyard to their hand. If you do, that player chooses a permanent card in your graveyard, then you put it onto the battlefield under your control.
You choose the target card in your opponent's graveyard as you put the triggered ability on the stack. That opponent chooses the card in your graveyard as the ability resolves.

If the card in your opponent's graveyard isn't a legal target as the ability tries to resolve, it will be removed from the stack and your opponent won't get to choose a permanent card from your graveyard.
