Wheel of DEATH and Kil'jaeden, mutual exclusive effects please

Simply as said: Wheel of DEATH and Kil’jaeden should be mutual exclusive in their effect… If you play Kil’jaeden and then Wheel of DEATH, your Portal gets empty and you start taking damage from the next turn on. If you play Wheel of DEATH and the Kil’jaeden, the Effect of wheel of DEATH get’s lost. How you will do it, it’s up to you.

I know, that in the moment this doesnt seem to be a problem, since there are much more faster decks dominating, but it has to disappear, in my opinion at least.

Thanks for reading …
