Hexdrinker is definitively a the better viper. I'm curating two cubes. One is for teaching beginners the concept of drafting/cube. The other one is hopefully becoming more important once said beginners have grasped the ideas and when they have learned all keywords, rules, and intricacies of nearly 30 years of magic. Let's be honest I cure my main cube more for fun, than for the number of times it get's played.
