(Written) INSTANT (SPELL-TRAPS/TRAP-SPELLS) CARDS!: A New Card Mechanic!

[skyline777123]

Hello! Welcome to another skyline777123 Card Mechanic! Today's Special may seem like an Old Idea, and you are right! But has anyone written a version of the Mechanic? I do not know. If anyone has, they probably have not come up with a name. So, without further ado, I proudly present: INSTANT CARDS!

...where are the cards?

You need to have at least 1 card in this thread and/or explain how the concept works.

I'm seeing neither of those, so will be locked.
