DZW - Chimera Clad

The monster effect "During your Main Phase: You can equip this card from your hand or your side of the field to a 'CNo.39' monster you control as an Equip Card" is an Ignition Effect that activates in the hand or on your side of the field. (This effect targets 1 "CNo.39" monster in your Monster Zone.)

The effect "While this card is equipped to a monster, that monster cannot be destroyed by battle" is an effect applied while "DZW - Chimera Cloth" is treated as an Equip Spell Card. (It does not start a Chain.)

The effect "At the end of the Damage Step, if the equipped monster attacked an opponent's monster and it was not destroyed by that battle: You can make that opponent's monster's ATK 0, also it can make a second attack on that same monster during this Battle Phase" is an effect that can be activated while "DZW - Chimera Cloth" is treated as an Equip Spell Card. (This effect starts a Chain. It does not target.)

An opponent's monster whose ATK has been reduced to 0 by the effect "make that opponent's monster's ATK 0, also it can make a second attack on that same monster" will remain at 0 ATK as long as it remains face-up in the Monster Zone.
