You guys will likely know this:
If I have Oracle en-Vec tap and target Player says "no attackers on my next combat phase" and then during their turn, I cast Siren's Call... do they (the non-wall / non-summoning sick) get destroyed?
Does the Oracle render them "not able to attack" and therefore not eligible for Siren's Call?
I have been playing assuming that they aren't able to attack and so it won't work, but the more I play the deck I have them in, the more I realize how valuable it is if it destroys their guys
Otherwise, I have to wait for other cards to complete the combo.
Oracle en-Vec text
Tap: Target opponent chooses any number of creatures he or she controls. During that player's next turn, the chosen creatures attack if able, and other creatures can't attack. At the beginning of that turn's end step, destroy each of the chosen creatures that didn't attack. Activate this ability only during your turn.
Siren's Call text
Cast Siren's Call only during an opponent's turn, before attackers are declared.
Creatures the active player controls attack this turn if able.
At the beginning of the next end step, destroy all non-Wall creatures that player controls that didn't attack this turn. Ignore this effect for each creature the player didn't control continuously since the beginning of the turn.
Thanks!
