Cast out bug
I was playing the Azor Control mirror match, but with decks slightly different. Mine is more oriented to Yorion and Omens, and opponent's deck more about the Narset and Memory combo. Opponent plays Cast out and exile my Teferi, Hero of Dominaria. Later in the game he plays Shark Typhoon, i try to catch a counterspell with Azcanta, but instead i get Heliod's Intervention. Shark Typhoon resolves and at the end of his turn i play Heliod's Intervention with X=2 targeting his Cast out and Shark Typhoon. The spell resolves and those two permanents are destroyed. My Teferi, Hero of Dominaria enters the battlefield with 8 loyalty counters instead of 4, letting me activate his -8 ability on my turn after.
