This is something that i've been curious about for a while now. Say I have an Injection Fairy Lily on the field. If i equip it with Shooting Star Bow, it now has 0 ATK.

But now, say I attack directly, and use her effect to boost her ATK by 3000. Does she hit for 3000 damage (assuming nothing interferes with the attack), or 2400 (3400 - 1000 from the Star Bow)?

Also, same kind of question, say I equip Injection (or any monster with 900 or less ATK points) with first a Star Bow (-1000 ATK), and then an Axe of Despair (+1000 ATK). Does the monster just revert to it's original ATK value? Or does the Star Bow 'set' the monster's attack at 0, allowing Axe of Despair to boost it to 1000?

Thanks in advance.

"Shooting Star Bow - Ceal" decreases the current ATK. So if "Injection Fairy Lily" is equipped with "Shooting Star Bow - Ceal" and activates her effect, her ATK is 2400 ((400 - 1000) + 3000 = 2400).

Axe and Ceal will basically cancel each other out.

Yep...Shooting Star Bow - Ceal, though it does not cause any ATK to go negative, it does keep full track of ATK and recalculates with Lily (as the ruling shows).

ok, cool. thank you both for clearing that up.
