I would rather say - stop hating RNG and meme cards.
They are already weaker and unviable in most cases. Alzur comes to break that tendency.
There's nothing wrong with RNG inherently, it will only become problematic if it reliably delivers way more value than other cards of same provision cost. In that case, its a balancing issue, but then again, you also have cards with 0 RNG involved and yet they're extremely overtuned.
In fact, RNG promotes the player's skill to adapt and adjust to each situation. I know this is not the case of Alzur, where you just get whatever its spawned, but other RNG cards like create, fall into this category.
I agree that the core of the new cards of an expansion should be more "serious", im ok with that as long as they belong to a well designed archetype and have original mechanics. But if its just gonna be 'do x dmg' and 'boost by y', and direct upgrades or variations of cards that already exist, i would rather take some quality meme content.
