Big proponent of dingleton (singleton, but all two-ofs).

My most frequently updated cubes are

• Peasant's Grave (peasant cube with strong discard/graveyard theme)
• Nostalgic Dreams (an »Old Border Masters« set cube)
• Fast & Furious cube (high tempo, low mana curves)

Other than that, I'm trying to figure out how to do 3-color cubes for 4 player drafts, especially ones that also feature tribal. Rough ideas include:

• Sultai Party featuring Merfolk, Elf and Zombie tribal alongside some other themes
• Peasant Abzan Cube, which is about finding glue cards to connect themes that are usually a bit lackluster or linear (lifegain, sacrifice, +1/+1 counters)
• Peasant Jeskai Cube, featuring obvious themes (spellslinger, heroic, blink), as well as some odd ones (draw 2, defender, tapped-matters)
• Abzan Party Cube, another Abzan cube, this time focussing on tribal
