As such, the Ancient is a key contributor to Experiment Kraj and Vorel of the Hull Clade decks, who love their counters. Skullbriar of the Walking Grave also loves the fact that the Ancient can give him additional fuel, since Forgotten Ancient can donate some of his counters. Animar Soul of Elements, Daghatar the Adamant, Ghave, Guru of Spores and Ulasht, the Hate Seed particularly appreciate the extra counters, as well. There are others that benefit from his counters, too.
If you can still pick up non-foil copies of any printing for $3 or less, go for it. Otherwise, if you want one for your collection or deck, you’ll want to hit up the foil. These have a chance to go nuts due to the low supply. While I highly doubt this sees any Constructed play, as it’s only legal in Legacy, Vintage, and Commander, I think the EDH demand alone should make this a really nice long-term speculation, especially the foils.
