For everyone else, if you can't think of any more mechanics, you could help us get started on filling out the deck skeleton with flavorful designs.
Criteria 2: Design three or four cards that represent aspects of Halloween. Try to make them generic enough that they can go in various kinds of decks.If you're wondering how to mechanically represent a flavor nugget, here are some things the deck needs:
- 2-3 small creatures (cmc 1 to 3).
- 3-4 mid-sized creatures (cmc 3 to 5).
- 1-2 large creatures (cmc 5 to 7).
- 0-2 combat tricks (could benefit your creature or harm an enemy creature).
- 1-3 removal spells (could be destruction, -X/-X, direct damage, or a fight effect).
- Possibly a discard or looting spell.
- Possibly a sweeper.
- Possibly a Fog or Panic Attack effect.
- Possibly a Naturalize effect.
Hole filling it is...
