Isareth does not show you her stored mana when she is in play.
Also what is the stored mana of a reinforced Isareth in play? Is it the original value of X? Or the new one? Or both?

Thank you for the report, this does appear to be a bug.
Regarding your question, the stored Mana of a Reinforced Isareth the Awakener will always take on the highest Stored Mana Value of all of the Isareth the Awakeners you played.
If you play an Isareth with 1 Stored Mana and then Reinforce with an Isareth with 6 Stored Mana, the Isareth in play will take on the value of 6 Stored Mana. Conversely, if you play an Isareth with 6 Stored Mana and Reinforce with an Isareth with 1 Stored Mana, the Isareth in play will keep the Stored Mana value of 6.
Ok, thanks! That seems an intuitive way to do it. I guess when the display bug is fixed it’ll be easier to tell how it works.
