Meria Has a Gambling Addiction (EDH / Commander)

The reason that I began pursuing this deck was because I wanted to try playing a deck that benefitted from using zero cost artifacts.

Meria herself gets maximal value in this sort of deck.

• Her ability to turn zero mana artifacts into rocks that tap for green is an ability that gets maximal value when the artifacts cost zero mana to cast.

• When your artifacts are cheap you run less risk of rouletting (meria's second skill: tap two artifacts -> impulse draw) into something so expensive that you can't play it.

And if you strictly follow the stats on edhrec it does seem like you will often see Meria built like this, where she is most powerful.

And while I do like cheerios artifacts as a concept, the fact of the matter is most of them are not very useful for your board state when Meria gets nuked from orbit. (Not a matter of 'if' but 'when', in a game of commander)

So for this version of the deck:

• added some higher cost creatures to allow us to actually stand a chance in combat. To note not all of them are artifact creatures. This loses us out on some efficiency, but I think makes us a little bit more resilient in the face of artifact hate.
• added some artifact based removal. Not removal for artifacts, but rather removal that is artifacts. Spending 8 mana to destroy target permanent with universal solvent is a far cry from swords to plowshares but for an artifact centric deck, it works. It only takes 1 mana to get universal solvent on the field, so hopefully it generates some value for you before you've ramped up enough to actually be able to sac it
• added some protection. Obviously the boots are in here, but the coolest tool here is: Null brooch which synergizes with this deck's often fairly empty hand.
• removed nearly all mana rocks. If meria turns all your artifacts into mana rocks then putting regular rocks into the deck has limited value. Unfortunately this means that you don't have the ramp to quickly recast your commander. Be prepared to have a rough time if you opponents run a lot of interaction.
• removed a significant portion of the stax pieces. Enough to be a nuisance, but not so much that someone's gonna throw a chair at you in real life. The ones that I left in are the ones that can be turned off by tapping them. Since Meria has a tap target artifact effect you can turn the symmetric effects off just before your turn.

As a result it takes a lot longer for engine of this deck to really get going, but at the same time I think it's a bit better at closing out games now. All you have to do is spin the roulette.
