Example 1:
Player 1 activates “Raigeki” but player 2 responds with a quick effect using “Spyral Sleeper” which destroys cards player 1 controls including “Raigeki”, so does “Raigeki” still resolve even tho it’s been destroyed?
Example 2:
Player 1 activated SS ENGAGE, but player 2 responds with SG UTILITY WIRE which sends engage to the top of player 1’s deck, so does engage still resolve because it wasn’t negated?
