just an idea, but if the engergize takes off harness the storm may be a good choice to clear the board of energy gems and turbo charges the spell to boot, normall it charges 3 but if a dovin or somebody else wants to do the work for you take it and show them how it is a 2 edged sword.
Volcanic Rambler and Volcanic Upheval are working against Aether Hub and Deadlock Trap since they’re likely to remove energy, but energized gems destroyed that way don’t count toward overload.
Electrostatic Pummler is a good, efficient energy generator that will do well overloaded with Olivia on the field, and Unlisenced Disintigration is a great kill spell. I’d suggest those.
