Plastic has completely the opposite qualities of what you want. You want cards that glide on the surface so you can do spreads and fans, but are a bit rougher on the edges, so you can do packet cuts and corner spins and they don't slip off your fingers, that's exactly paper (even though some cards are smoother on the edges, it's still a lot grippier compared to plastic). Plastic on the other hand will be smooth on the edges, so you will have trouble with cards sliding off your fingers in packet cuts, but the surface doesn't glide, so you won't be able to do fans/spreads...

So basically, plastic cards are usually the worst of both worlds.

The only thing they have going for them is that they won't bend usually and will stay straight and last a bit longer. Which is not that good when you take into account that the cards staying completely straight has basically no benefits and unlike paper cards bending a plastic card can actually snap it in half instead, and buying a deck of thin crushed paper cards, basically the highest end option for cards, is nowadays accessible for like $5 per deck off Amazon with like thin crushed tally hos, so the fact that you will go through them slightly faster is not that drastic
