Recently, we released a card named Ritual of the Elements. This card, when it produced a Lightning Titan, in combination with Leafkin Progenitor, often represented a combination that could win games easily, early, and without significant chances for interaction. Furthermore, it was relatively low risk to both add to a deck, and attempt to pull off. As such, we will be taking the following actions:
Starting at 12:00pm Pacific on December 16th, pending future downtime to implement balance changes, Leafkin Progenitor will be temporarily disabled in-game.
After we have had a chance to schedule and execute downtime to balance this particular interaction, Leafkin Progenitor will be re-enabled and restored to the collections of affected players. We apologize for the inconvenience and hope to have this fully resolved soon.
