(Sorry if this counts as a necro, but I thought it was important to say) Tragically, that won't work. When you attack with this weapon, the trigger to deal 1 damage activates and takes over the next timing. Your opponent can respond to that effect with their Shield and you cannot respond with your spell nullify, because of the two-effect-per-chain rule.

Legend World Heroes with their on-attack effects suffer this same problem with Breathen Gard.

>You attack with this weapon, effect to deal 1 damage to you triggers and waits for next play timing

>>Play Timing: Weapon's effect cuts in as "your effect". Opponent is allowed to use a Counter.

>>>Opponent casts nullify.

>>>>Reverse resolution: Nullify resolves, weapon effect resolves dealing 1 damage to you
