Codebusters is a lab and inquiry event in Science Olympiad.  It is new for the Twenty Eighteen Twenty Nineteen Season.  Popular types are Caesar, Aristocrat, Patristocrat, Vignere, Affine, and Hill ciphers.  I love Codebusters!  How about you?

I guess since the code has been decoded I'll start? Sorry if I'm not authorized to do so but I guess I'll make a new one.

Let's try a xenocrypt that's an aristocrat with hint if needed(Sorry non-Spanish speakers!)

Iqryo hqxbmy iz jeiqibri jeyteiqudy.

Note: First letter is capitalized

Hint: iz = el

Extra Hint since it's Spanish: This sentence regards one of the tenses.
