A 540 card cube i own. No power, but some powerful cards, such as fastbond, channel, demonic tutor, reanimate, tinker, good counterspells, efficient burn, and planeswalkers. Small side of tribal synergies among already premium creatures, and some great fixing (no OG dual lands, tho). If you're familiar with cube, you should get the gist quickly, but hopefully the experience will be fresh even if you cube all the time :)
