But the cards are no longer in play to update like your examples do. How can they update targets from the discard pile, that makes no sense.
Ok so dear battle my Joseph cow gets discarded does his protection of other sons of jacob stick till end of battle phase. I have had it ruled multiple times at states and regional that he is no longer on table to protect,
Uzzah specifies “all lost souls” so wouldn’t matter if a new lost soul enters play as it would still be included as being protected.However, Fire Foxes just says “lost souls” so only targets the lost souls that were available to be targeted when Fire Foxes activated. Any new lost souls added to the field would not be protected because they were not in play.
Based on the REG wording, I still see this as consistent. “An automatically targeted ongoing effect may update [...]” To day that it may implies that it also may not, which seems like it would be heard on the wording.
