This is one of the cards that will be desired by both Reap decks and colorless-matters decks. Because the extra cost is a little less punishing than Ugin's Construct (kind of? also the fact that it's common), I made the body a bit smaller to compensate.

I like the principle behind the design, though anything that may make land sacrifice before you hit like six or seven the correct play comes with issues I personally wouldn't put at common.

The difference to Ugin's Construct you seemingly don't account for though is that you sometimes don't need to sacrifice anything to the Construct e. g. playing it onto an empty board controlling only colorless lands.

This will always leave you with the decision to sacrifice either a land or itself. If anything the cost seems more punishing in its inevitability.

Yeah; this is a LOT cheaper than Bronze Horse, but sacrificing a land, just because you don't want to play green is a massive trap to fall into.

Still, no reason this can't exist; and maybe sone artifact-sacrifice deck can make use of it.

I too would be happier if it was rarer. Or maybe outright a rare with "Sacrifice a land: gain " would be a better way to play in the space?

Flavour is lovely though.

I agree that this definitely straddles the line between common and uncommon. Two points in its defense:

1. There will be a higher concentration of artifacts at common and uncommon, as it's a subtheme of the set. This also functions as another way to trigger Reap, so I'm hoping players see it like that.

2. There's going to be a lot of cards that punish you for playing it incorrectly or getting wrecked in the process of playing it. It's something that I enjoy in gameplay and design, and it's something that I'm emphasizing in this set.

I'm definitely alright with upping the cost and power on this though. If it turns out to be not what the Reap deck is looking for, I might change this to be a 6 mana 6/6 or 5/6 or something.
