Because cards from Portal: Three Kingdoms are so rare, their value is buoyed significantly by their rarity
For example, if you return a Copy Land that's a copy of Urza's Cave (a land with the types Urza's and Cave) to your hand to pay the cost of Wonderscape Sage's last ability, you won't discard a card
While it requires a bit of wheeling and dealing, you can likely talk opponents into letting you have whatever you want if theres a more obvious threat on the table
This card hasnt seen a lot of competitive play yet, but I wouldnt be surprised to see someone figure out a way to make it work
