CREATIVITY: 4 / 5
Your team has very interesting options in Counter Forretress, Yawn Empoleon, Swords Dance Mega Sceptile, and Specially Defensive Hydreigon with Toxic. These warrant a considerably high score in this criterion, though what holds it back from garnering a perfect score here is the latter's move choice (Toxic), which doesn't do much to its threats including Florges, Aromatisse (whom both do not care because of Aromatherapy), and Cobalion (whose Steel typing makes him immune to Toxic).
USE OF INGREDIENT: 3 / 5
The use of Choice Scarf Gardevoir doesn't fit well with this team, unfortunately. Its Healing Wish, while complementing Sceptile and Gyarados nicely (with Gyarados being worn out by Substitute later on), isn't absolutely necessary.
EFFECTIVENESS: 5 / 10
Unfortunately, while there are some creative touches to the team, it didn't translate much to its effectiveness. It is because the presence of the team isn't enough to handle some of the threats in the metagame, whether bulky or offensive. While there is some lack of cohesiveness in the team, you made a valiant effort to make a team out of a good concept. Keep working on that direction, and you'll eventually get there.
