Can someone explain the DLC to me?

[💋 💋 💋]

There are so many, what does what!?

Foils: Makes your cards shiny, cosmetic only
Keys: Unlocks all cards for a deck, convience dlc that stops you from having to play 30 games per deck to get all cards. I don't suggest buying it because you get a better feel for a deck when you are limited in the card selection.
Slots: Lets you get more sealed game slots so you can open more packs and create more decks, great if you enjoy playing sealed.
Expansion: Several NEW decks, campaign missions and challanges, usually worth five bucks.

also buying a key for an expansion deck does not unlock the deck if you don't have the expansion.

Hope this helps
