So let's say a card is played that does huge damage to everything (like Powered Shockwave when Unity has a lot of bots out) against Apostate with Relic Spirit on the table and only Runes of Malediction in the trash.
The attack hits the Relic Spirit, destroys it, and Runes of Malediction is brought out of the trash. The attack is still going on, so it then clobbers Runes of Malediction, destroying it. When it dies, it pulls Demons out of the trash, which would revive the Relic Spirit.
Does the attack continue by hitting the Relic Spirit, starting the whole thing over again?
What if Smoke Bombs are out, Visionary's Decoy Projection is the lowest HP hero target, and Visionary is the highest HP Hero target? Both cards say "Whenever X would take damage," so neither are once per turn. So wouldn't that mean if a villain target hits either, it will just keep being redirected between the two of them?
This is because each redirection can really only occur once. So, first the damage is redirected to the decoy projection, then it is redirected to Visionary (but reduced by 1). If it was damage to the Decoy Projection instead, it would go to Visionary (from Smoke Bombs) and then to the Decoy Projection, but reduced by 1.
