Forum:Chaos Emperor dragon- Evoy of the end possible fake rulling

I found this rulling and it looks fake to me, explain why it his not fake:

"You cannot activate other card effects during the turn you activate this effect." is not treated as an effect. (The effect of "Chaos Emperor Dragon - Envoy of the End" cannot be activated during a turn in which you have already activated another card effect.)[1] S.nickid (talk • contribs) 03:22, March 6, 2015 (UTC)
