However, as with anything else, the value of your cards still depends on the market forces for supply and demand
When you are going down the path of being mostly creatures, having a spell like Mizzium Mortars adds multiple powerful dimensions
Doing the math for exact market figures would be excruciating, so you may have to do some digging on Pricecharting to see whether this is a fair deal
Another thing that jumped out at me is that a lot of slivers have abilities that cost mana, and if we get too many in play it can start to become a burden
This deck is ideal for learning about the nuances of the combat phase, but also does well to teach about the importance of mana and establishing a solid ramp early in the game, thanks to 12 colorless artifacts, many of which are mana generators, and also through creature abilities like those seen on Weathered Wayfarer
