In a non-Goblin deck, this is exactly as good as
Tresserhorn Sinks. Maybe slightly worse,
depending on how likely it is you'll somehow
gain control of your opponent's Phyrexian
Ironfoot. But between Lorwyn goodies and the
general ubiquity of Goblins throughout the
history of Magic, most red-black deck are
already running a Goblin or two simply by
chance. And it isn't as though there aren't
enough good Goblins you might want to play, in
which case this is on par with Sulfurous Springs
as a mana enabler.
is Auntie's Hovel. It nets you either black or
red, but it comes into play tapped unless you
reveal a Goblin. It's a decent mana fixer for
Goblin decks running black, either the new
Lorywn goblin decks that want to run stuff like
Mad Auntie and the legendary goblin or the old
school ones running Patriarch's Bidding.
Otherwise, it'll just come into play tapped,
essentially making it a rare Urborg Volcano.
Part of a cycle of lands that each tap for two
colors of mana and come into play tapped unless
you show a creature of the correct type. This
basically speaks for itself in the sense that
it's great if you're running goblins, and not
too great if you aren't. Anyone remember back in
8th Edition when we had to put up with the
regular comes-into-play tapped dual lands for
two years, and they were hardly used? Yeah,
basically, just think about this card being like
those if you're not running gobbos.
In limited, I wouldn't bother drafting this, but
I'd use it in sealed if goblins was a big part
of my deck.
