Rakdos, the Showstopper

Rulings:

• 1/25/2019 Players can’t take any action between the time that coins are flipped and the time creatures are destroyed. For example, if they wish to cast a spell to have a creature gain indestructible, they must do so before Rakdos’s triggered ability resolves, without knowing whether that creature’s coin will come up heads or tails.
• 1/25/2019 All of the creatures whose coins come up tails are destroyed at the same time.
