Machina Resavenger — Ruling

Effetto 1

This card's effect that increases the ATK of a "Machina" monster on your field is a Quick Effect that activates on the field or in your hand. (It targets 1 face-up "Machina" monster on your field. It can be activated optionally during either player's turn. It can be activated during the Damage Step, but only at the start of the Damage Step or before damage calculation. Sending this card from your Monster Zone or your hand to the Graveyard is the cost to activate this effect.)

This card's effect that adds it from your Graveyard to your hand is a Trigger Effect that activates in the Graveyard. (It does not target. If a "Machina" monster in your Monster Zone destroys an opponent's monster by battle while this card is in your Graveyard, this effect can be activated optionally at the end of the Damage Step.)
