Theyre the rarest possible version of the card
It runs a few board wipes including Nevinyrral's Disk, but it doesnt seem to have an endgame besides to tick up Teferi and cast a big creature like Deep-Sea Kraken, Sphinx of Magosi, or the previously mentioned Lorthos, the Tidemaker
I think Alania, Divergent Storm is the best political otter commander, as gifting a card strategically is pretty sweet
Each one started off at around $3, but now the most expensive Nazgul sits at $18.75 (an increase of 547%) and the least expensive is $9.99 (a 242% price spike)
This is similar to the Lotus Field interaction, but more powerful, more consistent, and easier to include in any deck
Maybe thats because pretending to fight giant scorpions and the Kraken was just the thing for my friends and me on those long summer evenings when it gets dark before your bedtime
