To whom it may concern,

I was in a game of Traditional Standard Ranked, and a bug occurred that could have altered my games outcome.

On turn 3, I have a Leyline of Hope in play, A case of the Uneaten Feast, and a not summoning sick Resolute Reinforcements and its token.

I play the card Enduring Innocence, hoping to gain life from the creature entering from the Case's ability, to put me to 28 life from 26 life, and buff my creatures from the Leyline of Hope.

Upon the cast of my spell, my opponent cycles a herd migration, and his effect resolves, and my ability to gain life from a creature entering does not happen, as if it was stifled by the herd migration.

This appears a bug to me.
Ended up winning the game, but that could have cost me the entire game against Domain Control in Traditional Standard Ranked.

I hope this bug feedback helps! Feel free to reach out for more information.
Attached are the logs!
Thank you!
