? atk = 0 atk

Ok i am not sure if this had been posted in here...

but recently i needed to verify...
so i got my answer from ude offcial forum....

Answer:
When a monster with a "?" stat is in your hand, Deck, Graveyard, or
Removed Zone, the "?" stat is undefined. It is not treated as 0. ("Deck
Devastation Virus'" effect is an exception to this)
You cannot retrieve a monster with "?" ATK from your Deck with
"Sangan" because the monster's ATK is undefined. You can get a monster
with "?" DEF if its ATK is 1500 or less. (because you don't care what
its DEF is)
When a monster is face-up on the field, the "?" ATK/DEF value is
usually defined by the monster's effect. How is this is handled varies,
so it is best to refer to the card text and card rulings for the
monster in question.

So if you summon a monster with "?" atk, and yur oppoent activates skill drain, then how?
your monster's attack becomes treated as 0?

yeah correct,and IMO if u shrink mon with ? sttack ,u divide the current attack not divide the ? into 2 lol

but is it really their original attack? i think there are some cards that doesn't clarify whether the atk gained is counted as original attack, cards like great maju- gazett does, but if there ARE ards that don't clarify, then how? I'm sorry i don't mean to question your opinion i'm just curious
Yu-Gi-Oh is a weird game. and confusing sometimes
