3 "Elemental HERO" monsters Must be Fusion Summoned and cannot be Special Summoned by other ways. Once per turn, when this card is targeted for an attack: You can make this card's ATK become double its current ATK until the end of the Damage Step. At the end of the Battle Phase, if this card battled: You can target 1 monster on the field; destroy it. When this card is destroyed by battle or card effect: You can target 1 Level 8 or lower "Elemental HERO" Fusion Monster in your Graveyard; Special Summon it, ignoring its Summoning conditions.
What a power creep man ! who needs Bujin Crane if you have this one, even if it gets destroyed you get to summon a high level monster. It's technically like a bujin crane effect fused with ultimate ancient gear golem lolol
- first effect, ATK doubles only when attacked, not when it attacks.
- second effect has a major drawback : You CANNOT destroy Core itself with its own effect, revive an E-Hero Fusion, then attack again with it, since the effect activates at the end of Battle Phase, not at the end of Damage Step.
- last effect requires an E-Hero Fusion in your Graveyard as target, meaning you have to fusion summon an E-Hero Fusion first and have it be dead first. Remember how "ignoring summoning condition" works when the special summon is from the Graveyard.
