Wait, what's a sticker cube?
The single greatest fan-made format I’ve ever heard of.
@mtg-peasant came up with this gem. They don’t seem to be around anymore from what I can tell but you can search their blog for “sticker” and get a lot of relevant stuff such as:
Here’s the long and short of it. Cube is straight garbage, nothing great in it, the whole thing was bulk I had an maybe $10 of singles. Each player who shows up to draft gets two stickers in sleeves with an indicator of what types of cards they can go on. As you draft or deck build, you apply stickers to cards, chaos ensues. Stickers range from “Haste” to abilities pulled off of planeswalkers to mana symbols to change colors of abilities or casting costs. If players want to, they can bring another garbage card and swap something in their pool for thie new garbage they want to play with. In reality people have been incredibly generous with their additions, I figured it’d be homelands commons, but there’s a few neat rares that have snuck in there. Most powerful cards are either Lightning elemental (RRR for a 4/1 Haste, shadow, double strike, lifelink, cantrips on etb and has echo) or the elegant but simple Mulldrifter (4U for a 2/2 Flyer, etb draw 2, evoke 2U, 1U: return to hand, Cascade).
Also here’s an image they posted of prepping stickers for the cube:
There’s another post where they share a google doc of their sticker sheets but it doesn’t seem to be around anymore. I really need to get my own sticker cube going.
