Use Massivemorph on your opponent’s monster to increase their Attack, and use Swordswoman to attack into it, while protecting your Swordswoman with Half Shut during your Battle Phase and deal Life Point damage to your opponent.
You can make your Amazoness monster immune to battle destruction for one battle phase while it is attacking or being attacked while Amazoness Onslaught is active on your field. The gets rid of the monster you battled while keeping your Amazoness monster alive. But keep in mind you will receive more damage because your monster's attack will be cut in half.
This spell card can be activated at Damage step.
When a monster that this spell card targets becomes face-down, the monster can be destroyed by battle.
Your monsters lose ATK / Your opponent's monsters lose ATK
Only cards that affect the ATK/DEF can be activared in the damage step (e.g only Kunai with Chains second ATK boost effect can be activated in the damage step).
Half shut affects the ATK by halving it so its a damage step card.
Flip monsters get flipped as soon as the damage step start
I activated "Wall of Disruption" on Dakini. Next turn, I activated "Half Shut" to get my GB effect. But after the turn was over, Dakini´s ATK went back to the original, disregarding the effect of "Wall of Disrutpion". Shouldn´t "Half Shut" restore the half of ATK at the end of turn instead of full restore?
I seem to have found a bug with this card and the Malus Token from The Golden Apples. The token was at 2300/2300 and was targeted by Half Shut during my battle step. The ATK was directly halved, but was reset to 0 at the end of the turn rather than back to 2300.
