now I do see shard of wisdom as an interesting turn, but its still a creature. The idea of playing a deck with no creatures is a powerful powerful strategy, and one that shouldn't be done away with. consider you can make decks with no spells. no pillars. no permanents or weapons and win. the idea of having a deck with no creatures is not only viable but sound. nerfing this play style outright is not so great, in fact it takes away from the game as a whole.
t least 100, if not 200 or you take away from the game in an unalterable way, there is no way around it if these limits remain.
