That's not very good, Psybeam is a weak low powered move without stab, and doesn't cover anything.
Shadow Ball also won't work too well with Surskit because it doesn't cover anything.
Bubblebeam is a low powered move, not the best idea.
Signal Beam is good though.
The moveset should be this:
-Scald - Stab, good power, good accuracy, chance to burn. Or -Hydro Pump - Great power, low accuracy, STAB.
-Signal Beam - Stab, good power, good accuracy, chance to confuse.
-Giga Drain - Good power, recovers HP.
-HP Fire - Good coverage
Or maybe if you wanna take a move out of those for
-Ice Beam - Good coverage, good power, chance to freeze.
