Derricrane Train De Fret Lourd MP17-FR118

If one or more EARTH Machine-Type monsters are Normally or Special Summoned to your field (except during the Damage Step), you can Special Summon this card from your hand, but its original ATK/DEF will be halved. You can only use this effect of "Heavy Freight Train Derricrane" once per turn. If this card is detached from an Xyz Monster and sent to the GY to activate that monster's effect, you can target 1 card your opponent controls and destroy it.
