For example, if a zombie with
Vendread Revenants's effect chains banish effect to your Solid being summoned, if you shuffle Solid, his effect won't activate. If you let Solid be banished, his negate won't activate either.
From the second person's comment what I understand is this:
He summoned Solid, before he received the prompt to target negate the Zombie his opponent used his quick effect "banish a special summoned monster".
Case 1, he shuffled Solid using his effect n°2. Since he was shuffled his 1st target negate effect can't be activated any more.
Case 2, he didn't activate the shuffle effect of Solid. Thus Solid gets banished before being prompted to target negate using his 1st effect. Since Solid is not on the field anymore but is in the banish Zone instead his effect cannot be activated anymore.
My two assumptions would depend on if "being face-up on the field" is a necessary condition for a "if + can" to activate.
What a detective.
Yeah, WSotA was destroyed during my opponent's turn. My Solid was summoned during his turn, not mine. I suppose he had "toggle on" and was therefore able to activate his target banish "in response to Solid being summoned" right before Solid activates his target negate, due to turn player priority.
Perhaps shuffling Solid makes him "not public", like being face-down=No effect.
