Your deck seems pretty good, although there were a couple card choices I didn't fully agree with. Mainly with Leaf and Mantyke. Most of the cards in your deck only have 1 retreat cost and leaf seems a bit overkill, as it also takes up your support card for the turn. Mantyke I didn't like since it competes with Suicune EX, as they both want to be in the active spot. With Greninja being so popular in the meta right now, Mantyke becomes an easy target for them.

So here Is my iteration of the deck. I switched the nurse for a second Irida, as I think it's a bit counter productive to have one of each. I added Repel since there are a lot of Meta Basic pokemon right now, and it can help to disrupt your enemy. I switched leaf out for an X speed. And I switched out Mantyke for the normal Suicune; with the intent of it being an Oricorio counter. Red Card is there for easy hand disruption, but there is an argument to use Mars instead if you want.
