It could go up in value if our post-rotation format is heavy on the flip-into-lands enchantments or a cycle of creaturelands sees print in the future, although for now, it's probably best to use a couple of copies of Field of Ruin to answer the stray Search for Azcanta or Arguel's Blood Fast, since Field of Ruin doesn't put you down a card
If a card like The Abyss is out of your price range, you can also pick up at a much cheaper cost on Magus of the Abyss
Avenger of Zendikar One of the great classics of Commander top-end, Avenger of Zendikar loves the ramp-centric game plans in the format
Not background necessarily, but some other line of text that says something along the lines of Whenever you sacrifice a Treasure token, give a creature a +1/+1 counter and trample until end of turn. That would make it a lot more interesting and powerful, but I suppose not every card needs to be great
The card shows Giratina in its original form, cruising through the distortion realm
We'll want to work around that discard limitation, though, and so a Bag of Holding is a decent inclusion here
