Treason Phantom

The following effects can be used once per Duel: ● Reveal a total of 2 "The Phantom Knights" monster and/or "Phantom Knights" Spell/Trap Card from your hand, return one of them to your Deck, and send 1 "The Phantom Knights" monster from your Deck to your Graveyard. During this turn, you can treat "The Phantom Knights" monsters as Level 4 monsters when you Xyz Summon "Dark Rebellion Xyz Dragon." ● Remove 2 Xyz Materials from 1 "Dark Rebellion Xyz Dragon" you control, and increase its ATK by 500 until the end of the turn. During your opponent's next turn after you activate this effect, you can activate your Xyz Monster's effect only one time.
