10+ years later, collectors will pay above the odds for one of the only top graded copies of that card in existence
This tells me Defense Grid was the card they would have played on the previous turn and Lotus Petal was their topdeck
It's essentially a sorcery-speed Unsummon that sticks around, which isn't exciting but could be useful in the right deck
Being the only game in town for no-art lands would make Unstable more similar to Unhinged or Unglued , where if you wanted a certain subgroup of basics for your deck, you pretty much had to buy the set (or at least the lands from the set, which would force someone else to crack a box of the set to sell them to you)
It also led to abandonment and disposal of ordered food
