A *LITERALLY* UNTAPPED RESOURCE Convoke, conspire crew, harmonize, saddle, and now station: these are the mechanics which allow you to pay costs by tapping random creatures you control
Thats tragic
Obviously, you are only running Mirabel in a Madrigal deck and, as I've already noted, I don't think that deck is going to be competitive
Across the 37 new Tyranid creatures in the deck, there are plenty of ways to build not only a wide army but a tall one, with the ability to cast naturally large creatures and pump up your little ones with extra counters
And it's a bomb in a Bloomburrow draft, so you're always happy to see it
Note that if it cannot be countered the Jin won't stop it, like Last Word or Supreme Verdict
