The Immortal Sun has certainly spiked with the announcement of 36 PW's in the next set. Not sure how long it'll stay up in price.
not cards that are high priced but cards that will go up
Yea, because it's not possible for them to go up more in price.
well it wil maybe go up but it is already high so it might not go up much
As you can see,
sliver queen has
gone up in price a lot, almost overnight. It was a steady $35 for a while. It more than doubled to $80 for a time. It was already high, but it went up even more.
The immortal sun hasn't increased much since I bought mine, about $7, so it isn't like I was super lucky with timing or anything. I wouldn't mind paying another 7 bucks if I had to get it today, but I would most certainly not buy a
sliver queen after that price spike.
So to
void your argument, cards that are high in price can go up even more, and by a noticeable amount. I'm sure there are plenty of other examples across the inventory of mtg cards, but
sliver queen is the first one I could think of.
