This is a multi-part question because I have no idea how to predict the interplay of effects of two cards:
Probably I'm missing some basic timing rules information.
(Also, if the answer would be different prior to 9th Edition or so, I'd like to know both answers as pretty much all of my cards are that old so I tend to prefer the older rules for casual games.)
Several situations I'm wondering about:
Let's say I've played Abduction on one of my opponent's creatures (doesn't matter what for this question, call it creature A). Then, when the creature is about to be destroyed in combat with creature B (either as an attacker or a blocker, if it makes a difference I'd like to know both), I play Enchantment Alteration and move my Abduction to creature C.
What happens to creature A? Since it's no longer enchanted, I think it wouldn't be put back into play under owner's control, right? But would it be taken out of combat since I don't control it? Would creature B be saved from being killed? (Let's say creatures A and B are both 2/2s.)
Also, would creature C be untapped by moving Abduction onto it?
What if I moved Adbuction onto creature B instead? (From one creature in the combat to the other?) Or from a noncombatant to an enemy combatant?
Overall I just need to understand how transition of control affects combat, and also in particular whether moving Adbuction off a creature right before it dies prevents the "put into play under owner's control" effect of Adbuction.
