To be honest, it's not a very good deck, especially for tournaments.
- Biggest flaw would be that you have way to many high star cards.
- Another thing, you shouldn't use support cards in half decks, let alone in a 3 clan deck.
- Amy and Zdrone aren't very good cards, I think you're at a high enough level to be able to afford something a little better.
I'd suggest you use a different deck if you want to do good in tournaments.
If I were you, I'd try something like this -
The deck you have right now is somewhat fragile, the cards don't exactly have great synergy (Bridget is nice with Jungo but the Sentinels don't exactly fit well with them)
