I do believe functions such as "scrying" did the job of stacking quite well.
Commander always was my favorite format, where one card was "stacked," in a manner of speaking.
But none of those matters are relevant here.
The only matter of importance is whether AST receives more impacting functions as we progress further into game iteration.
The answer to that question is not in dispute.
The presentation of such functions are reminiscent to holding a hand of cards. You may not like that presentation, and by all means use whichever sequence of language you desire to mock such an idea, but no manner of choice on your part will change that presentation, nor will they contribute to elevating the game's difficulty.
I will say as I have said many times and remain resolute in so doing- If you take issue with the game lacking difficulty, address the game lacking difficulty. Your efforts are wasted if not applied to the correct issue.
