We've had a discussion and YES it will be banned for CRL for this month. https://twitter.com/SaintBelikin/status/1401863474695884800
@rick_c_official will goblin drill be banned from crl this month? Last year, when a card was only available from special challenges it was banned from CRL, will it be the same this time?
Not much we can do here for this.
Logging into the game before the update (like me), we had the previous reset formula as the new update had not yet been released.
Unfortunately, we did lose more trophies; however, we did get some extra rewards.
We need to push a little more now
