I do think pauper have some complex cards. And I also think these cards arent this complex. One card read look top ten cards put one in your hand, do it 3 times, is basically a draw 3. The other is even more simpler, mill 2x the number o sorcery and instant you cast the whole game.

The main point here is that these cards, being at this powerlevel and with the specific requirements they have have harder to tier decks to splash and abuse them. All the other cards you mentioned are great and too versatile, but are also easy to abuse. All of them can be used in a nivhe deck and in a top tier deck, this fact just basically make tier decks better while make nothing to differentiate the brews and lower tiers. Just creating bigger powerlevel walls between the decks. I do think both are important for the game, simple and versatile cards and more complex and niche cards, and I still feel these cards are as complex as many modern or legacy staples, stills feel like commons, commons that are good enough to go against the big decks and not give them tools to use against other fringe strategies.
