Hi everyone, I’m trying to build decks for a custom format using this card pool (f:standard tix<=0.1 usd<=1). I have a deck here: deck link.

I know legality is ultimately whatever rules you define for a custom format, but I’m looking for a practical way to check a deck automatically against a specific pool, rather than checking each card one by one. For reference, Penny Dreadful has a deck legality checker. I’m wondering if there’s something similar for generic card pools, or if manual checking is the only option.

Is there an easy way to check if the deck is legal for this pool and identify any cards that aren’t allowed? Also, I’d love tips or strategies for making deckbuilding simple in a custom format like this. Thanks!

    Seems simple enought, so I’m going to try and make one myself. Here’s the idea I have so far:

    1. User selects a default format or uploads a JSON list of legal cards.
    2. User pastes decklist text or uploads deck JSON.
    3. Script compares deck entries with legal list.
    4. Output = list of illegal cards.
