Loyal Cathar - When Loyal Cathar dies, return it to the battlefield transformed under your control at the beginning of the next end step.
Question reposted from user Zacula:
I believe that Cathar's ability is not a delayed ability that triggers at End of turn. The ability reads: "When Loyal Cathar dies, return it to the battlefield transformed under your control at the beginning of the next end step." It is triggered upon Loyal Cathar's death! it doesn't say: "If Loyal Cathar dies, at the beginning of the next end step return it... blah... blah... blah...
From the rulings, a triggered ability begins with the words "at", "when", "whenever". Loyal Cathar's aility triggers upon its death, so it is up to the controller of the two triggered abilities (Undying, and cathar's) to place them on the stack any way he/she wishes to. He will of course prefer the Undying to resolve first, hence the result will be the same as everybody else answered to this question.
My question is: am I right regarding the Cathar's ability not being a delayed triggered ability that triggers at the End step?"
