Jodah, the Unifier bug
There is currently a bug with Jodah, the Unifier done recently in my Competitive Brawl game. The Jodah effect went to exile a legendary spell with lesser mana value and hit Gwen Stacy//Ghost Spider. Only Gwen Stacy was within the mana value required but my opponent was able to cast the reverse side for Ghost Spider which was 2 mana more.
1. Step 1: Jodah, the Unifier on the battlefield, Step 2: Cast a legendary 3 or 4 mana spell, Step 3: Exile Gwen Stacy or possibly another dual sided card with different mana costs with Jodah's effect, Step 4: You are now able to cast the more expensive side even though it has higher mana value.
I am on Steam.
Opponent(Player) is able to cast the more expensive side of a spell exiled with Jodah.
Player is not able to cast the higher cost side of the card as Jodah's ability explicitly states you may cast the exiled a card with LESSER mana value.

"That last part was what got you. I think that situation lets you choose the card Gwen Stacy because when exiled from the library its mana value is always 2, but then when your opponent got to cast it for free it doesn’t check the value again and the option is given to cast either side for free."
Correct.

I’m not a judge, but unfortunately I think this is a situation where the rules as written are just unintuitive. Quoting in part from google’s AI summary on the mana value of double-faced cards:
2. Modal Double-Faced Cards (MDFCs)These cards feature a small triangular icon in the top left corner of both faces, allowing you to cast or play either side from your hand. Each face has its own mana cost: When casting or playing a modal card, it functions like a standard card for that specific side.
On the battlefield or stack: The permanent or spell has only the mana value of the face that is being used.—> In your hand or library: The card possesses the mana value of its front face.
That last part was what got you. I think that situation lets you choose the card Gwen Stacy because when exiled from the library its mana value is always 2, but then when your opponent got to cast it for free it doesn’t check the value again and the option is given to cast either side for free.
