I’m not sure if this is still the case, but it used to be that if you had any foils in your deck and took it to a tournament, you had to either foil the entire deck, or replace all foils with non-foils. This became problematic for cards that were only available as foil, like M19 Nexus of Fate (from what I remember).

Personally, I only play casually anymore. Foils don’t matter to me at all. If a card is foil, then it’s foil. If it isn’t, then it isn’t. I only care about its playability.

Some foils do bend really badly, but I’ve been fortunate enough not to run into that problem yet.

Hate when they curl and hate when the treatment is so poor you can’t read them or make out the art. I do like a lot of the newer premium treatments that don’t have those issues, and those are nice. But I specifically avoid “standard” foiling for singles, and I’ll even pay more in the rare case that foils are cheaper.

I won’t play with them and always trade them of they’re valuable. The only time I ever play with them is in limited, and I hate it.

I live in a dry environment and they curl an insane amount in less than 5 minutes. They curl through sleeves, and even double sleeves. You can uncurl them in a tupperware with a wet sponge for a few days, but they will not stay flat so what’s the point.

I like foils if I have them, but I don’t really go out of my way to chase them. I double sleeve my commander decks, so most curling isn’t an issue, but some cards out there are really bad. I’ve had them curl immediately upon opening a pack.

If I’m buying a card for a deck, I’ll probably go foil or special art, but it depends on the price. I play casually with friends, so it’s more to show off cool cards with them.

I’d rather not have foils because they’re more delicate and I have to take more care to prevent them from curling.

When I used to play constructed formats, I’d sometimes entertain the thought of getting foils of only certain key cards as a signal to help me recognize them faster. I had a similar thing with my old Modern Tron deck, where my Tron lands were the only white-border cards, so they were really easy to pick out while searching my library. I never ended up doing that with foils, though.

Depends, would prefer a deck to be more consistent, if it has foils it should have lots. Also depends on the card itself, some it suits them well like when they are a flashy illustration, others it just makes them hard to see.

The Pringle problem is real though.

Avoid when possible. In general, I like their special artwork less than the original. Yes they’re shiney, but somehow less colorful. Also mildly harder to read. And yes, the curling issue.

I dislike using them inside my decks because of how often they curl. However for my Commander I will often try to spend the extra money for an extra shiny card since they almost never get shuffled into the deck

However I am a little disappointed how often the foiling is just not that impressive. Coming from playing Yu-Gi-Oh as a kid I do miss their more bombastic foil cards

I avoid them as much as possible due to the curling and bending and glare when playing with sleeves on them.

I tolerate them because it’s not worth spending more money on a non-foil when I pull one, but if I’m buying singles I go out of my way to not get foil.

It’s just not good quality and gives nothing to the card that I care about
