My board: 5 lands, Cauldron Familiar in graveyard, food token
I want to play Massacre Girl and sweep up opponent's board. With no other creatures, Massacre Girl's trigger doesn't do anything, so I need to bring back Cauldron Familiar first. But opponent has a Shock, so if I bring back Familiar and then cast Massacre Girl, they will Shock in response to my Massacre Girl and the trigger does nothing.
Here's my plan:
- I will cast Massacre Girl.
- Once Massacre Girl enters the battlefield and triggers, in response to the trigger, I will bring back Cauldron Familiar.
- Opponent can now Shock the Cauldron Familiar, but since Massacre Girl has the line of text "Whenever a creature dies this turn, each creature other than Massacre Girl gets -1/-1 until end of turn" and it is already on the battlefield, it doesn't matter, the Phoenixes get -1/-1, and Massacre Girl sweeps them up anyway.
Does this work, or does this ability on Massacre Girl not matter until the trigger is resolved?
