Ru-Pani Market

Sacrifice target artifact: Place X market counters
on Ru-Pani Market, where X is the total mana
cost of the artifact -1.
{t}: Remove X counters from the Ru-Pani Market.
Add {X} to your mana pool when paying the
casting cost of an artifact spell.
When two or more groups of Ru-Pani meet-up
at sea, or in port they will gather together into a
larger flotilla. Trading, storytelling, and other social
activities ensue for several days.
