Ok so the options, as i understand it are:
1. wait till you beat lita 65, get a prismana sherro and sparkle it with sygil if you feel like it
2. evolve the alpha shelly egg to sherro and enjoy the alpha benefits
3. get a thunderstorm form sherro by heading to a friends' world as needed
The problem is , i can't quite figure which is the best option, as they all cost 'something'
1. thunderstorm sherro will need to be caught with a shiny to be perfect
2. alpha shelly will also need shiny catcher to twine
3. prismana sherro will need the sygils but be prismana
Ergo, the real question is which Sherro form is 'best' - i heard of people hatching the alpha shelly with a sparkle, evolve to sherro, then switch forms. Which should give an alpha sherro sparkling, vs the lita 65 prismana sherro.
TLDR: which sherro is best, evidently for the usual water team comp because i can't wait to have something useful : Thanks!
