• Since you're playing all cats, Kaheera, the Orphanguard is a must include.

• I personally believe Leonin Warleader and Regal Caracal can be a bit too heavy for the curve. Maybe consider cutting two of each and replacing those cut for four copies King of the Pride.

• Even though it costs just , Outflank is a but too condition. A good replacement would be Kabira Takedown  ^Flip. It's more expensive, but you can cast it at anytime and it can serve as a land if you need.

• Because you're Monowhite, Sundering Growth is better than Disen Disenchant. You can use Populate to get copies of Embalm tokens.

• Since you want something for the side, two or three copies of Watchers of the Dead should be great against graveyard decks.

• Maybe cut a bit of removal to include any amount, depending on your preference, of Leonin Relic-Warder, Felidar Cub or Enlightened Ascetic. They may not be as versatile, but they can benefit from the lord and the anthem.

• As for lands, I'd recommend Shefet Dunes as a high priority. Secondarily, you could think about Sejiri Steppe, Sandstone Bridge, Windbrisk Heights and Idyllic Grange. Don't if any of these will interest you, but I hope at least one can be useful.

• If this deck goes against a lot of removal, maybe Abiding Grace could be a good sibeboard card to reanimate Charmed Strays.

Hope this wall of text doesn't bore you to death!
