To say that To My Side! and Rhok'delar are unique cards is an understatement. Together, the "no minions" condition present on both cards appear to push Hunter in a direction no (viable) Hunter deck has ever gone: an archetype which runs zero minions.
As it stands, however, there is a gimmicky loophole to the "no minions" condition, one which runs very few minions with the condition that they be destroyed by the time you play To My Side! and Rhok'delar. It involves running only minions that cost 3 or less, then using Hemet, Jungle Hunter to destroy all minions in your deck.
For the combo to work optimally, there cannot be more than 4 minions starting in your deck, including Stitched Tracker and Hemet, Jungle Hunter. This is because of Stitched Tracker, included to make drawing Hemet, Jungle Hunter more consistent. If there are more than 4 minions in your deck at the time you play Stitched Tracker, there is a chance you will not Discover Hemet, Jungle Hunter.
After we throw in Stitched Tracker (2) and Hemet, Jungle Hunter (1), we have room for 1 other minion in the deck. Cloaked Huntress was the most intuitive choice. Given that this deck strips away many cards (namely Beasts) that have been staples of Hunter's early game, Cloaked Huntress creates the potential for one explosive turn to both set up Secrets and fully activate Lesser Emerald Spellstone.
As stated, this deck is gimmicky by design; the sole purpose is to theorycraft a fun deck in which To My Side! and Rhok'delar have the best chance to thrive. Feedback is appreciated, but keep in mind that viability is not my top priority. Sometimes we play decks simply because we can.
