1 Tuner + 1+ non-Tuner monsters During your opponent's turn (Quick Effect): You can target 1 Fusion, Synchro, Xyz, or Link Monster on the field, or if your LP are lower than your opponent's, you can target 2; destroy them. You can only use this effect of "Gold Pride - Eradicator" once per turn. Once per turn, during the End Phase, if the previous effect was activated this turn: Return this card to the Extra Deck, and if you do, Special Summon 1 "Gold Pride - Eliminator" from your Deck or GY.
