Looking for Carven of Souls, Canopy Vista, some cheap cards and trades

I'm looking for:

1 Cavern of Souls
2 Canopy Vista
1 Submerge
2 Rough // Tumble

I'm also sort of looking for Modern/Legacy infect cards if you have any of those.

If you don't have any of these and see something you're interested in, feel free to propose something anyways and I'll see if I can find something.
