Brain Freeze + Lotus Petal + Underworld Breach

Overview
With Underworld Breach on the battlefield you may cast Brain Freeze from your graveyard by paying its escape cost (its mana cost plus exiling three other cards from your graveyard). You can activate Lotus Petal’s mana ability before casting Brain Freeze to help pay the mana portion of that escape cost; sacrificing the Petal moves it to your graveyard so it can be one of the “three other cards” you exile for escape. When you cast Brain Freeze (from the graveyard via escape) its Storm triggered ability will trigger and put copies onto the stack equal to the number of other spells you’ve cast earlier this turn; activating Lotus Petal is a mana ability, not a spell, so it doesn’t increase that count . The copies are created by the Storm trigger and are put onto the stack — they are not cast — and when they resolve each copy mills three cards .
Step 1
Activate Lotus Petal’s ability to add one mana of a color you need and pay the activation cost (tap and sacrifice). Because this is a mana ability you may activate it before paying a spell’s costs .
Step 2
Sacrificing Lotus Petal moves it from the battlefield to your graveyard (it is not a spell when sacrificed).
Step 3
Decide to cast Brain Freeze from your graveyard using Underworld Breach’s escape ability. Follow the casting steps to cast a spell from the graveyard (casting from a zone other than your hand is allowed when an effect says so) .
Step 4
Determine and pay Brain Freeze’s escape cost: pay its mana cost ({1}{U}) — you may use the mana produced by Lotus Petal — and exile three other cards from your graveyard as part of that cost (the sacrificed Lotus Petal can be one of those three) as required by escape.
Step 5
When Brain Freeze is cast, the Storm triggered ability triggers and creates copies of Brain Freeze equal to the number of other spells that were cast before it this turn; note that sacrificing Lotus Petal was an activated ability, not a spell, so it doesn’t increase that count .
Step 6
The Storm trigger puts the copies onto the stack (you may choose new targets for each copy). Those copies are created on the stack — they were not cast — and so they do not themselves cause Storm triggers .
Step 7
Resolve the original Brain Freeze spell and each copy in turn. Each resolution mills the chosen target player for three cards. After the original Brain Freeze resolves, it is put into its owner’s graveyard as the final step of resolution .
Step 8
Cards milled into your graveyard by Brain Freeze (original or copies) are now in the graveyard and, because Underworld Breach is in play, those nonland cards have escape available for future casts (subject to their escape costs).
Resolution
You may sacrifice Lotus Petal for mana, have it go to your graveyard, then cast Brain Freeze from your graveyard using Underworld Breach’s escape by paying {1}{U} (you may use the Petal’s mana) and exiling three other cards from your graveyard (the sacrificed Petal can be one of them). When you cast Brain Freeze this way, its Storm trigger will put copies onto the stack equal to the number of spells you cast before it this turn (activating Lotus Petal is not a spell and doesn’t increase that number). The copies are created (not cast) by the Storm trigger and each copy mills three cards when it resolves .
