I think Hs need a new type of card, a card that you can have 2 like normal cards, but only play/summon 1 per turn, maybe call them elite cards ¿?, cards like lamplighter or zilliax, this cards are fine if you play 1 per turn
Maybe other cards can be like Cressendo of warlock come to mind, they play the 1/3 you are inmmune and then to huge waves (and maybe with lifesteal)
Just an idea that come to mind, With this you can have powerful cards but no exploit them using them a billion of time. what you do you think HS forum?
English is not my 1st lenguage, srry for any misspell
