Forum:Unaffected by card effects question

I've got a question that came up in a duel scenario, so I'm using a Constellar deck and I have Constellar Omega and Constellar Kaus out.

Now I've already used the effect of Omega this turn making my constellar monsters unaffected by spell/trap effects and my opponent controls Number 39 with xyz wrath on the field. I activate the effect of Kaus for the second time when he is level 5 to make him 6 can my opponent chain Xyz wrath to negate the effect of Kaus? or since my monster is unaffected by trap effects does the effect still go through?

Also separate question, if my opponent destroys call of the haunted targeting my monster with MST is it possible to negate the destruction effect of call of the haunted with Stardust Dragon?--Eternumblaze (talk • contribs) 03:29, May 19, 2014 (UTC)
