There are actually a lot of ways the exile zone gets used in regular gameplay across all formats
I also wonder about Monastery Siege
This engine, however, along with the Dark/Rocket, Gym, and Magma/Aqua ones, are rather weak nowadays when compared to mixing and mashing the best of cards from all sets EX Legend Maker (this set has some nice Stadiums) EX Legend Maker Cursed Stone Stadium: Any time between turns, each player places on damage counter on any Pokmon with a Pok-Power
Bristly Bill, Spine Sower and Scythecat Cub have incredibly high price tags because theyre relatively hard to replace, but other cards that put counters on your creatures like Hadana's Climb and Nissa, Voice of Zendikar can work
I also had a water energy card in my hand, and so I defiantly decided to give that to Seaking instead
