Magic Carpet and Magic Rose (Munchkin Disney)

[Cammagno]

Hi,
I have a question about these two cards.
They are One-shots (they have the icon and the "usable once only" text) and giving a combat bonus they are supposed to be used in combat.
But they also have a peculiar limit (on your turn you are supposed to roll a die and maybe suffer a curse) and the first also has a Disney Magic that lasts until the end of the turn...
so I'm confused, because these two things seem more compatible with a slotless equipment item.
If they are One-Shots as stated, when am I supposed to apply that limit? If they are on the table each turn before they are actually used? Only in the turn in which they are actually used, but when I'm the active player?
And that Disney Magic effect is mispelled and should only apply to he combat in which the item is actually used?
TIA for your opinion.
