During your opponent's turn, when your opponent declares a second direct attack during the same Battle Phase, you can Special Summon this card from your hand. When you do, this card's ATK and DEF becomes equal to the ATK and DEF of the first monster that attacked directly this turn, if it is still face-up on the field. The turn this card is Special Summoned with this effect, your opponent cannot select monsters other than this card as an attack target while this card is face-up on the field.
Use Lava Golem to give your opponent a powerful monster that burns it’s user. If you are lucky your opponent will attack with Lava Golem first so that you can special summon this monster with 3000 attack.
