I definitely keep Flame Shock and LvB around just for Maly Phase 1 -> Phase 2 transition and for the Heigan dance. Dancing got boring, so I started doing Flame Shock + LvB during the dance phase. The timing is perfect so that you can Lava Burst on the end safe zones then follow up with a Flame Shock for the next LvB. Plus it's just fun to play with overall, big numbers!
