Does "Exile 2 target permanents" allow exiling a permanent shrouded by another permanent?
Example:
Player 1 controls drannith magistrate that is shrouded by lightning greaves
Player 2 casts ulamog, the ceaseless hunger and thus triggers its first ability "Exile 2 target permanents"
> can player 2 exile drannith magistrate and lightning greaves?
No. Targets are chosen when as spell or ability is put on the stack. Only legal targets can be chosen at that time. The Magistrate is not a legal target due to being shrouded by the Greaves.
Example:
Player 1 controls drannith magistrate that is shrouded by lightning greaves
Player 2 casts ulamog, the ceaseless hunger and thus triggers its first ability "Exile 2 target permanents"
> can player 2 exile drannith magistrate and lightning greaves?
