Life Extreme (POTE-EN099) - Power of the Elements 1st Edition

Equip only to an EARTH Synchro Monster. If the equipped monster battles an opponent's monster, the opponent's monster loses 1500 ATK during that damage calculation only. Once per turn, if a monster's battle position is changed (except during the Damage Step): You can target 1 card on the field; destroy it. If this card is sent from the Spell & Trap Zone to the GY: You can Tribute 1 "Power Tool" Synchro Monster; Special Summon 1 "Life Stream Dragon" from your Extra Deck. (This is treated as a Synchro Summon.)
