I've played
a lot of
kessig cagebreakers, and really like the card. Its been a consistent, excellent, presence in every one of my low power formats. Its a card very deserving of a low power spotlight, as its the perfect pushed card for those types of formats, and exactly what I want from a rare: a powerful effect that looks and feels pushed when its triggered, but very beatable due to the amount of setup that goes into getting that trigger, and encourages synergy.
If you untap and get to the attack step, its power is relative to the degree you were able to craft your deck to enable creatures being binned. It tends to not just end the game, in the same way a craterhoof would, and you would be surprised at how poor some decks are at getting creatures in the yard--its less of a reasonable assumption than player's often think. Because the cagebreakers has to attack to generate the tokens--and is a mediocre body--it can die in the attack, leaving the opponent ready to crack back, or clean up the wolf tokens. The decision to attack or not attack can be surprisingly complicated.
That being said, I didn't want to automatically suggest it for your format, as I wasn't sure how good of a fit it actually would be. Beating the mana trade drum again, this is another brick creature, costed at the awkward 5, that has to untap and get to the attack step to do anything, and frequently has to survive to a second attack step to really close out the game. That means it has to both survive removal and the board as a four toughness threat, to close things out, which is kind of tough.
Thats a lot of conditions, and traditionally I like it to be at the higher end of the format's power spectrum--if not at the apex--as otherwise players start to ask why they should bother jumping through all those hoops, once they realize it doesn't actually play like craterhoof.
Its miles better than the other cards you have listed, however.
