The bug is: Copies generated by Lazav, when exiled from hand, do NOT charge beacon bolts in the graveyard. it may be all copy cards; confirmation needed
How it should be: Even with the change to “COPY” clause, the act of exiling from hand (before the copy is removed from the game) should trigger “Jump-Start”
Right. As of now only exiling non-copy cards charge my jumpstart cards in the graveyard. I have seen this with Thousand Year Storm with Doppelganger/Beacon Bolt. I don’t have Lazav, but using him would follow the bug’s pattern.
