Time Engine

(This card is always treated as a "Metalmorph" card.)

If a monster(s) you control is destroyed by battle or an opponent's card effect: Target 1 of those monsters; Special Summon it, then if you Special Summoned a Level 5 or higher Machine monster by this effect and have a "Metalmorph" Trap on your field or GY, except this card on the field, you can apply this effect.

● Destroy as many monsters your opponent controls as possible, then you can inflict damage to your opponent, equal to that Special Summoned monster's original ATK.
