This card can serve as a substitute for the pre-errata "Chaos Emperor Dragon - Envoy of the End". Tribute Summon this card using "Chaos Emperor Dragon"( and another Monster, if you want), and copy its effect. While you won't be able to use "Chaos Emperor Dragon's" Nuke/Burn effect on that same turn, you will be able to during your other turns. And since said Dragon's condition is not an effect, you will be able to use its destruction effect and other effects during the same turn.
This card is most effectively used for gaining the best characteristics of 2 monsters: a monster with a strong effect, but low ATK/DEF values and/or a debilitating effect, and a monster with high ATK/DEF values and/or an effect that counteracts the debilitating effect.
By Tributing "Lyrilusc - Independent Nightingale" for its Tribute Summon (easily Special Summoned by "Instant Fusion"), this card will not only be unaffected by all other card effects, but also have 6000 ATK and be able to inflict 5000 damage per turn.
By Tributing a Special Summoned "Obelisk the Tormentor", this card will gain its effect while also avoiding "Obelisk" from being sent to the Graveyard during the End Phase.
By Tributing "Hardened Armed Dragon" alongside with "Obelisk", this card will be immune against targeting and destroying effects.
