[MasterOfMagicians]

Name: Convergence of Powers

Type: Trap - Continuous

Effect:

This card gets the following effects when the specified monsters are face-up on your side of the field:

Blue Eyes White Dragon - All monsters on your side of the field are unaffected by the effects of Trap Cards.

Black Luster Soldier - All monsters on your side of the field are unaffected by your opponent's monster card effects.

[XENOCIDEX]

you do not have to say that if none of the listed monsters are present, the card does nothing as those effects only can activate while those specific monsters are on the field
