How are you speeding up her totem with the Handler? Pretty sure the Handler's Aura doesn't apply to the Purifying flame, because it's an enforcer.
The card says- Goad Witchling: Friendly Witchling Minions that Activate within (6) gain +2 Mv until the end of their Activation.
The only thing I see that affects the Purifying Flame is her defensive trigger, since Consolidate Power is minion specific as well.
