Both are versatile for the fact that your units can drop these artifacts at any location/region
Thats why Ive always wanted to build a mono brown deck in 93/94 so I wanted to share my initial thoughts about this and why I actually havent done this yet
Note that there are exceptions
There's still more though, as Goldspan Dragon also makes it so that you can sacrifice your treasure tokens for two mana instead of one
Decks that often play Wasteland include tempo decks like Delver that require very little mana or decks with Life from the Loam and other ways to recur it
To that end, there are big spells in here, like Maelstrom Wanderer, Omnath, Locus of Rage, Titan of Industry, and more, all of which can be used to grab big ETB triggers to keep opponents on their toes.
