Who Should I replace?

Hello- So this is my team and I have a feeling that I do need to change something about it, I am thinking about replacing Haxoros with Lairon because I need a steel/rock type and I already have a dragon type. I was going to get Delta Axew for its steel/water, but I accidentally killed it. Any advice? I am at Sonata City and I haven’t fought the trainer yet.
Current Team:

You could switch your haxorus for a ground type to counter electric.
Then, you should take a steel type indeed. Instead of your scyther.
At your point, lucario is not so bad.

What do you think of it?

i could trade you a delta axew if you want
