"As though it had flash" is currently not functioning for split card halves. This should be fixed this week.
If you're curious, it's because when you're casting a split card, you're actually "CastLeft"ing or "CastRight"ing it. The rule-code for "as though it had flash" was mistakenly explicitly only working for Cast. #wotc_staff.
Just to make sure, "as through it had flash" should work correctly with spectacle, jump-start and aftermath, right?
Correct.
