Overview

With Green Goblin (the back face) on the battlefield, its Goblin Formula gives cards in your graveyard mayhem and its other static ability reduces the cost of spells cast from your graveyard; Necropotence’s triggered ability (“Whenever you discard a card, exile that card from your graveyard”) will trigger when you discard, but that trigger goes on the stack and can be responded to — so you can cast a just-discarded card from your graveyard for its mayhem cost before Necropotence’s trigger resolves, provided timing rules allow it and Borne Upon a Wind has given you permission to cast spells as though they had flash (; Ruling [2023-06-16]; Ruling [2017-11-17]; ).

Step 1

You have Green Goblin face up, Necropotence on the battlefield, and Borne Upon a Wind's effect active for the turn; you cause or allow a discard to happen (for example, you discard a card via an effect).

Step 2

The discard event happens: the card is put into your graveyard. Triggered abilities that watch for a discard (Necropotence's "Whenever you discard a card, exile that card from your graveyard") are triggered and put on the stack.

Step 3

While Necropotence’s triggered ability is on the stack (but before it resolves and exiles the discarded card), the discarded card currently sits in your graveyard and — because Green Goblin’s static ability gives cards in your graveyard mayhem and the card was discarded this turn — it is eligible to be cast from the graveyard for its mayhem cost ("you may cast a card from your graveyard for its mayhem cost if you discarded it this turn").

Step 4

If the card is a type that would normally be restricted by timing (for example a sorcery or a creature), Borne Upon a Wind’s "cast as though they had flash" effect can allow you to cast it at instant speed; Goblin’s "Spells you cast from your graveyard cost {2}

less" also modifies the spell’s cost while Green Goblin is face up. Ruling [2023-06-16]

Step 5

You may cast the discarded card from your graveyard in response to Necropotence’s trigger: you announce the cast, choose to pay the mayhem cost (and any additional cost modifications apply, such as Norman’s cost reduction), then the spell goes on the stack and resolves if not countered.

Step 6

If you choose not to cast (or are unable to cast) the discarded card before Necropotence’s triggered ability resolves, that triggered ability resolves and exiles the card from your graveyard (after which it is no longer in the graveyard and cannot be cast from there). Ruling [2017-11-17]

Step 7

If Necropotence exiles a card face down (from its other ability), you cannot look at those face-down exiled cards while they remain face down. Ruling [2023-09-01]

Resolution

If Norman is the Green Goblin face up (so Goblin Formula and the cost-reduction static ability are active), and you discard a card this turn, that discarded card will have mayhem while it’s in your graveyard and you may cast it from your graveyard for its mayhem cost — but Necropotence will trigger to exile that discarded card. Because the exile is a triggered ability that goes on the stack when you discard, you can cast the discarded card from your graveyard in response to Necropotence’s exile trigger (so long as timing rules allow that cast). Borne Upon a Wind’s “cast as though they had flash” effect can let you make that cast at instant speed if needed, and Norman’s “Spells you cast from your graveyard cost {2}

less” applies as a continuous cost-reduction while Green Goblin is face up. If Necropotence’s exile trigger resolves first, the card is exiled (face down if exiled by Necropotence’s other ability) and can no longer be cast from your graveyard (; ; Ruling [2023-06-16]; Ruling [2017-11-17]; Ruling [2023-09-01]).
