Bug - Improper Strict Proctor Resolution
My opponent has a Strict Proctor in play. I have five untapped mana, and a Skyclave Apparition in my hand. I cast Skyclave Apparition, targeting the Strict Proctor with its ability, which triggers when it enters the battlefied.
In turn, Strict Proctor triggers, prompting me to pay 2 mana or counter the ability. I pay the 2 mana to allow my ability to resolve, and the Strict Proctor counters it regardless, resulting in the Strict Proctor remaining on the battlefield after I spent 5 mana to remove it. I checked the graveyard and exile-- no other cards were used to interact with triggered abilities.
Strict Proctor was hard-countering my deck, and I sat there for 5 turns in order to save the mana to remove it properly in my ranked game, only to have the game bug out and leave it in play even after my exile ability resolved... Extremely frustrating.
I see that this isn't the only error involving Strict Proctor's ability, which is very frustrating since it sees a lot of play. I took a screenshot, but it's missing from my clipboard so I will list everything that was in play.
Total list of permanents in play:
Opponent - Island, Island, Hallowed Fountain, Hallowed Fountain, Lotus Field, Strict Proctor, Teferi Hero of Dominaria
Me - Mana Confluence, Overgrown Tomb, Overgrown Tomb, Forest, Lunarch Veteran, Deep-Cavern Bat (nothing exiled), Gilded Goose, Skyclave Apparition.
