Discard 3 "Blue-Eyes" monsters from your hand to Special Summon "Montage Dragon" with 7200 ATK, then activate this card to revive one of them from your Graveyard.
If the equipped monster is removed from the field before this card is, it will not be banished and will avoid this card's drawback.
Use "Imperial Iron Wall" so the summoned monster will not be banished, or leave the field, if "Beacon of White" leaves the field.
The best monster to Special Summon with this card is "Blue-Eyes Ultimate Dragon". It has the highest original ATK among the Blue-Eyes and has no effect to be negated, plus you can Tribute it to Special Summon "Blue-Eyes Shining Dragon".
As long as the target was properly special summoned first, monsters like "Blue-Eyes Toon Dragon" and "Malefic Blue-Eyes White Dragon" can be special summoned by this card. Even though this card has a couple of its own drawbacks, any negative effects of monsters such as these two examples would not be an issue (including their respective self-destruct effects).
