For Volcarona
Use Giga Drain instead of Silver Wind for a lot more coverages and it covers Water, also you already have Bug Buzz as your Volcarona's STAB move.

For Swanna
Use Ice Beam instead of Fly since you can change Ice Beam to Fly at anytime (you can also change Fly to Ice Beam at anytime by using Tm). Tailwind instead of Roost to support your team.
