Having problems with this one. To get the last point you need to energize a ton of gems. No problem there except she drops the gonther heart tons-o-swaps / nuke you each gem combos. Even when I get control of the board she drops that and then I sit there for 5 minutes watching her swap endlessly until I die. I tried harness lightning to clear the gems but she re energizes so quickly herself it's a one or two turn respite at best. It feels like my options are "just beat her" or "try for the energize challenge and fuel her combo for her".

Clearly it's a doable challenge, I'm just having a rough go. Any strats or tips y'all can give me? Thanks much.
