Use this card to destroy two "Crystal Beast" monsters on your side of the field and activate their effects. Then, use "Crystal Beacon" to summon "Crystal Beast Ruby Carbuncle" from your Deck, thus allowing you to Special Summon the two destroyed "Crystal Beasts" back onto the field again.
Destroying your monsters is not a cost, so while you control "Archfiend Zombie-Skull" and another Zombie monster you could destroy your opponent's monster without suffering negative effects.
Use this card to destroy Yubel or its evolutions while not losing field advantage.
If your Monster Card Zones are clogged by any means, for example if you opponent fills your last Zone after you tributed "Stardust Dragon" for its effect and it would be unable to return, you can use this card to free up your slots as well as destroy one of your opponent's monsters.
You can chain this card to cards like "Raigeki" or "Lightning Vortex." Since your monsters are about to be destroyed anyway, you can use this card (or multiple copies with a full enough field) to take the opponent's monsters down with them.
