@joshuabrooks said in Need some creative help and ideas for a new format (Wild Card Commander):
I might consider just going with cards that either have massive (affects everyone) effects, or go with targeted removal or interesting creatures.
(Given my experience may not equate to yours.) This is the most dangerous part. The players shouldn't be able to rely on the pile for things like wraths and removal because then you can build a deck with none of them and just lean on the pile. Making the pile consistent in any way is the single thing I found most enabling of the troubles.
