Snake Trap is a must in this kind of a deck. Also, spellstone is the best way of generating tempo for hunter right now cuz playing cheap beasts on curve (like mole+adapt+whatever) does literaly nothing against druid or warlock right now. Playing spellstone is better even in aggro matchups.
+ stitched tracker is a must for finding cauldrons. SO spellstone + snaketrap build is also better this way, because you also may include less minions thus finding your cauldrons with trackers easier.
TL;DR: too lazy build.
The idea is fun though and i like cauldrons a lot
