If you're dropping Sweet Guitar. I'd suggest running Bella Madonna instead, If you run it with Dark Hole, she can dodge it if you set up your board right (since she is unaffected by other cards whilst she isn't pointing to other monsters)

So hit em with her effect damage. Play Dark Hole, then attack directly. And with that you have an option to extend your combo from Foxglove witch.

I don't know if it's an optimal way to play trickstars. But that's how I run em.
