Functional lands are always highly praised and useful
Considering that the 30th Anniversary Edition is, what many players consider to be, proxies, or illegal game pieces that replace a much more expensive alternative, many players did not believe that there would be any value in this product
Its name is functionally impossible to pronounce, it has no casting cost, when its played (by discarding it), it fetches a book from your deck, and it has an ability that sacrifices food to force creatures to hurt themselves
This can make activating the Portal every turn automatic, and thats a good way to win the game in a hurry
Harmonize Harmonize is a perfect green sorcery for ramp decks in Commander, and decks centered around the next card will likely run it, so the second and first place go in hand
This card can easily attack as a 3/3 or 4/3 for just 2 mana, and with max speed, you get to copy artifacts for cheapjust icing on the cake
