Forum:Mask Change VS Book of Moon

For example, my opponent has an Elemental HERO Sparkman face-up, and active Mask Change targeting Elemental HERO Sparkman, and I chain Book of Moon on Elemental HERO Sparkman flipping him face-down.

Mask Change still works or his effect simply dissapears? RichardMuto (talk • contribs) 06:51, April 22, 2012 (UTC)
