Foundry Inspector (11/14)
Cost reduction is always a powerful effect,
and Foundry Inspector offers that rather neatly,
making all your artifacts cheaper. Given the
Kaladesh emphasis on the card type, it makes a
lot of sense to have this effect. What I’m less
keen on is that it’s a fragile body (3 power is
okay, 2 toughness is not so good) that’s a bit
awkwardly-placed. Etherium Sculptor from Shards
of Alara might be the better actualization of
this effect; it asks for blue mana, but there’s
a huge difference between 2 mana and 3 mana for
this sort of effect.
Don't get me wrong, Foundry Inspector isn’t
bad. But it’s underwhelming in practice because
of its spot on one’s mana curve, and I feel
you’d be better off spending 3 mana elsewhere.
It may have a home in artifact-heavy Commander,
though, because one can't have too many versions
of effects that let you cheat on mana costs.
