Comments

Don't use False Swipe. If they are at low enough health that False Swipe will leave them at 1 HP, Fell Stinger will usually be able to get the KO anyway. Replacing it with Drill Run so you can get Fire types may be a good idea.

In my opinion, Wish instead of Healing Wish is a good idea since you can heal your team and yourself, but that's your choice.

Not exactly a rate, but if you're struggling to ladder, then you could try having a look at the most used pokemon right now, and if any of the top 20 or so propose threats, then you should prepare for them over more obscure threats.

You ignored some of my suggestions for Tyrantrum. Life orb is better than sitrus berry.
