My general playing strategy is almost every plunge is a skill shot into the witch unless there's a big priority available like needing ECMB right this second, or a munchkin mode available that I need. I'll let those go directly to the right flipper. Anyway in normal circumstances I'll then finish the hurry up from right flipper and more or less pray the magnet doesn't whip the ball impossibly into the left drain. Do a bunch of YBRs to get the flying monkey activated, Dorothy captured, start haunted modes, get EB1, and probably get Lion and Tin Man activated. Backhands to main ramp for the Scarecrow. By the first ECMB ideally you have an EB, a munchkin mode, and all three witch hurry ups done.
Play ECMB1, try to complete, try to bring in a crystal ball mode for them points, if you get extra lucky you'll get a second EB from the throne shots, and after that I do fireball frenzy and then focus on Rescue.
Games where I pay attention to YBRs and hitting the right orbit go magnitudes better than ones where I focus directly on ECBM so I basically prioritize YBRs now. I've got the game on factory settings except the outlanes are in, and there's a short ball saver at the start of each ball.
