Each time a "Resonator" monster(s) is sent to the Graveyard as a Synchro Material: Target 1 card your opponent controls; destroy that target. Destroy this card during your 2nd End Phase after activation.
Destroys your opponent's Monster Cards / Destroys your opponent's Spell Cards / Destroys your opponent's Trap Cards / Destroys itself
Finally a decent use for Red Rising Dragon. With Destruction on the field, summon RRD with a Level 2 Resonator, pop one card, activate RRD's effect to bring the Resonator back, then summon Red Dragon Archfiend to pop a second card.
If you have two of these on the field at once, your opponent's field becomes a fireworks display.
