You can play Nashi in rat decks or legends-matter decks, and its useful to cast value rats, those that enter the battlefield and make your opponents discard
That does some wild stufffor example, it gets Marsh Flats back twice for actual land ramp in Orzhov, it lets you feed cards like Dusk Legion Zealot into a Warren Soultrader multiple times, or it wrings the most value possible from cards like Boromir, Warden of the Tower and Dauthi Voidwalker
For those who arent familiar with the Monopoly money found over the border, thats about $22,000 USD
For example, Mickey Mouse - Detective is considered a different card than Mickey Mouse - Playful Sorcerer
When fal'Cie from Gran Pulse, the feared lowerworld, are discovered in their midst, the Sanctum government of Cocoon orders a Purge to banish anyone associated with them
Its also slower than Birthing Pod since you cant use its ability the turn it comes into play without giving it haste
