I opened a wilds of eldraine booster box then created a cube out of it plus some purchases and upgrades I had in my collection. This is cube is now draftable will see a future balancing and a small decrease in size.

Check blog tab for reasoning on adding/removing cards

Green cards with “top card” tag were in the top 50 Elo cards for my cube.
Yellow cards with “signpost” tag are cards that are key for different archetypes.

: good removal, small creatures, life, control, board wipes, enchantments
: good draw, counterspell, tempo, bounce, tap, make creatures on board useless, some big creatures
: good removal, GY utilization, pay life, generically good cards
: good aggro, efficient but red heavy removal, burn, some big guys
: good ramp, THE big guys, creature based removal, enchantments

Combos:

hatching plans + bargain card

Up the beanstalk + mulldrifter or any 5+ cmc card you card for less.

cauldron familiar + witch’s oven

twisted fealty or Eriette’s Tempting Apple + sac outlet like vampiric rites or costly plunder

sun titan + quest for the necropolis to create a wall of reanimation. You just keep returning the enchantment back and if sun titan dies, you reanimate him. This is hard to beat.

necromancer’s magemark + neva, stalked by nightmares

gadwick’s duel + hymn to tourach
