I seem to have run into a bug with the Cult of Rakdos support, in the right node of the Rising Tensions event. The support is written:
At the end of each turn, if your opponent lost life during that turn, all cards in your hand gain 2 mana.
This effect was never triggered. I believed I had made a mistake of some kind at first, but I made sure to use cards that specified “lose life” effects rather than “damage” effects. Using an event deck slot for Sorin, Grim Nemesis, I used the cards:
Highborn Vampire
Dina, Soul Steeper
Vindictive Vampire
Revenge of Ravens
Krydle of Baldur’s Gate
Tenured Inkcaster
God-Pharaoh’s Statue
Poet’s Quill
Brightclimb Pathway
Swiftblade Vindicator
The event support for the node was never activated, despite each of the “lose life” effects being used. This occurred on an iPhone X running iOS 15.3.1.
If there’s any further information I can provide to help reproduce the issue, please let me know.
