Keep in mind this card can still be used as a Tribute. If you were to normal or Special Summon this card to the field, you can immediately use all of your "Kurivolt" as Tributes for a monster like "Obelisk the Tormentor".
If you plan to Tribute Summon a monster like "Obelisk the Tormentor", using a card like "One for One" can allow you to gain 3 "Kurivolts" without using a Normal Summon.
Use with "Galaxy Storm" to bring down a powerful Xyz Monster.
Use this card to detach 1 Xyz Material from "Evilswarm Ophion" to make its effects ineffective so that you can special summon Level 5 or higher monsters (But your opponent can special summon again also).
