Let me pop this into the collective consciousness of the AH community:
With the advent of the Edge of the Earth permanents (which all severely muck with your deck at 0 XP), where does versatile stand?
Should it be taboo'd down to 0? Should the number of new level 0 cards be changed from one to two so you can at least run a playset?
I think both. Versatile has a lot of problems as a design: Adding one card to your deck and increasing its size by 5 creates a very intense anti-synergy that makes it hard to justify this card. Likewise, being 2 XP to downgrade your deck in most ways is rough, and the only way to justify it is if you built your deck around a card you lack access to and you seriously risk never drawing it outside of Seeker.
But the idea of being able to get just ooooooone playset of a very useful card into the 'wrong' type of deck is very interesting, but the cost of 5 extra cards is pretty extreme on its own in a way that is not intuitive until you run the math.
At the very least one of these two things could stand to be changed. You have a little under 50/50 odds of getting what of getting the thing you paid 2XP for and ruined your deck probability to nab even with two copies on a hard mulligain, but at least that is remotely likely compared to going hard for your single splash and only finding it maybe twice a campaign in your opener as a 28% snag. Or if you could start with it you can build your deck more appropriately around those extra cards and you get at least one more chance to find that card you hurt your deck to get.
