Jeskai with howl of the horde

[delregnr]

How does a copy of a spell interact with jeskai ascendancy??  Example
creature with prowess (seeker of the way) on the field and a jeskai ascendancy. And I cast howl of the horde and declare my attackers.  Then I cast an instant. And copy it once.  How many times does prowess and the ascendancy activate ? My guess is three times each.  So a 2/2 with prowess becomes an 8/8 ?

For reference: {Jeskai Ascendancy} and {Howl of the Horde}.

I hate to be the bearer of bad news, but you would only get ascendency triggers for the spells you cast and not the copies.

You cast {Howl of the Horde}. {Jeskai ascendency} triggers untapping {Seeker of the Way} and giving the +1/+1.

You cast {Feat of Resistance} two triggers hit the stack, one for {Howl of the Horde} and one for {Jeskai Ascendency}. Regardless of how you choose to stack them, the "copies" caused from Howl appear on the stack and are not independently cast.  So provided no other spells you get +2/+2 from ascendency, +2/+2 from prowess making a 6/6 until EOT.
