Once during your opponent's turn, if Ho-Oh would be Knocked Out by damage from an attack, you may flip a coin. If heads, Ho-Oh isn't discarded. Instead, remove all damage counters, Special Conditions, and other effects from Ho-Oh. Then, discard all cards attached to Ho-Oh (except for Energy cards). This counts as Ho-Oh being Knocked Out and your opponent takes a Prize card.
This attack does 20 damage times the number of different types of basic Energy cards attached to Ho-Oh.
