It's not format-breaking or anything like that, but it does feel like a surprisingly solid budget deck
This card is currently selling for around $220 on TCGPlayer
There are several cards in the First Print Run which have errors in text on them
It still looks like a fantastic Commander for a popular type, however
That said, between ramps ubiquity in Commander, the fact that ramping one land for 2 mana has been good enough for many cards to see consistent play in the format for years, and the risk that Deep Gnome Terramancer will be a dead card is minimal at best, and Id call it a safe bet youll come out ahead far more often than not when playing this card
That last bit means that it's basically not worth including in formats that aren't Commander, so it feels odd to see it shoehorned into the set instead of kept to the side in the Commander decks
