but was warned if I bring it she would bring some crazy formation that would table me turn 1.
Try "Up to 9 Riptides (3 squads of 3) who can fire twice (once per game if they don't move), reroll their Nova Charges, and get +1BS per prior Riptide that has shot at the squad they're shooting at."
I wouldn't say "I'm playing 150 Infantry," let her build her list, then pull out your tanks--that's flat out lying. I would say "build your list and show it to me before I show you which miniatures I've brought today." She cannot justifiably have a problem with that, so you should be in the clear as long as your minis aren't openly visible.
What sphinx of plascrete and adamantium bashed open their skulls and ate up their brains and imagination? Imperator! Imperator!
