Forum:Mech Memory

Why do Majestic Mech - Ohka, Majestic Mech - Goryu, and Malevolent Mech - Goku En have their effects activate if they have previously has been flipped-down/removed and replaced on field/had aility negated and reengaged? I know that Skill Drain Decks use cards like Beast King Barbaros and it uses "memory" of being summmoned but the card rulings on the first three say they will still be destroyed...? Why is this? --LordGeovanni 08:54, February 26, 2010 (UTC)
