multiattackers (apparently, based on this and other interactions) definitely don't behave like a special ability. For instance this seems to indicate they treat all their attacks as just plain attacks that everyone is subject too. But then mind stealers who state that the player card does damage to itself instead of the mind stealer when it attacks it, doesn't prevent other cards from also getting attacked, implying that each attack is seperate. OH, and if you boost a lightning clouds attack with an orc chieften ice golems take the additional damage too, so apparently abilities affecting powers that would effect a card work, even if the abilities themselves wouldn't on their own. I feel like theres one more important note to be had here, but its escaping me. Anyway, hope that clears things up at least a little.
