The Pork Futures Warehouse

Counts as Snowfield Sinkhole
{t}: Add {w} or {b}.
Snowfield Sinkhole enters the battlefield tapped.
The trading in pork futures - pork which does not
exist yet - led to the construction of a warehouse in
which to store it until it does. Pig carcasses can be
seen hanging from its ceiling, semitransparent and
unreal.
