Its basically a how to play guide booklet with in depth explanations of decks and deck setups
I've got a few extra bits and pieces to deal with organization, bulk, and color coding in my setup as well (more on that below), but if you're starting out as cheap as you can, you only really need the first two items on this list
Indomitable Creativity (red), Jund (black/red/green), Death's Shadow (black/red/blue), Rakdos Midrange (black/red), and more decks make use of this discard spell to absolutely hose opponents playing burn or other hyper aggressive strategies
When there is a golden ring around the number, it means this card is eligible to be placed into your Inkwell as Ink
Now you can have card sleeves that protect your favourite cards from wear and tear, but look like youre not using any card sleeves at all
