Playing a game of powered cube and my opponent cast a sheoldreds edict while I had a coalition relic on the stack and a ignoble hierach in play untapped and non-summoning sick, it did not pass priority back so i did not have a chance to tap my ignoble hierach for mana. This caused me to not have the mana to play my outland liberator that turn, oppo followed up with an oko to snowball the game since i didnt have any board presence due to the bug.
