That, my friend, is gold! Need to write it down.
But onto the point: Lillie is better than sycamore; however only exclusively to decks of a similar style to vespiplume. However, note that in vespiplume, sycamore is better cause you run revitaliser (cause of compressor) and because you want to discard stuff for damage. However, in a deck that turbos a stage 2 grass type that doesn’t use vespiquen and doesn’t exist in a format with access to battle compressor, say Tsareena, lillie is better than sycamore. This is what I have found from testing.
