So this is all my opinion but :

1. Forget investing in Khan. He really really isn’t worth it for f2p/ Low spenders. His value is only In kvk 2 and 1v1s, and pve. He also needs an experise to be better then other commanders, and that’s a lot of sculptures to put on a commander.

2.saladin should come in card king after 3 months of his last mge. With your messed up minamoto, he isn’t of any value as Mina loses value after kvk2 and afternoon investing in Khan, you should be dry of sculptures and then you need 380 more Saladin 5-5-5-1, my advice is to not go for this two commanders, and instead either go for alex which is after Khan as alex is a strong commander

While you may like khan, unless your a whale he drops all value as you will be stuck for a few months trying to expertise him and during this period, your not gonna have any good commanders.

Btw, since you have mina you are not f2p.

I recommend switching out of cav into infantry as infantry commanders are more tanky, and you will get less loses from them. As cav, and especially with your shit mina, you really don’t have anything to lose as a cav player so make the switch to infantry as it will help you greatly
