Hm, so, if I overlay into Gaia Dragon and then Quasar gets sent to the Graveyard, it's considered missing the timing since the last thing that happened was Gaia getting summoned? I guess that's fair enough.
Why does this also apply to Exa-Beetle's effect, though? When the two cards get sent to the Graveyard, Quasar's effect should activate. Is this also somehow considered missing the timing?
