The Undying card and how broken it really is in LoR

During a game in Runeterra whether this is intended or not when you make copies of the undying card via ephemeral from kalista or what ever spell card like the 0 cost card fading memories it will come back into play even though it has died due to the base affect of The undying card. Can argue sure there's a way to beat it by killing the opponent before they ramp up. The only card that can defeat them is she who wonders but good luck making it that far while they still have 4 or less ap. The card itself is annoying but I'm unsure if it was intended for the COPIES to continuously come back to life with the ephermal debuff. The debuff should overwrite the undying its like the champion tryndamere but not a champion pls fix this or at least change the interaction between how this card is effected. That or change how the copying cards work by only the base stats and removing text like the purify spell card. Now if you say just use the purify card I will remind you that you can only have 3 while making copies of cards can be triple that. To have all 3 in your hand in wait is more about luck at that point and to counter a deck be relying on having those 3 cards at all times is not right less thats whats this is going for and if so end the game before 8th round or so against that type of deck otherwise you will lose I guess is the theme. Just a salty player sharing an unfavorable experience.
