So, Hooru control updated for set 6. I'm not sure whether or not this list is optimal, but I went off my teammate Erik's original list, then tinkered around with interaction and survival cards. Ultimately, I don't think that there's any particular right or wrong way to build the deck so much as preferences. Run your choice of cheap interaction, your 4 harsh rules, your card draw, and then season the top end and market to taste. Svetya's Sanctum pulls its weight, but a 5-drop do-nothing is always going to be an issue when playing it. Other choices may include Sediti or Rost in that slot.
Anyhow, it's been running fairly smoothly for me, so feel free to take it out for a spin and let me know how what changes you'd recommend.
