I kinda disagree with that when speaking about hybrid creep\swarm decks.
Truth is, when you’re going hybrid your swarm cards can generate much more creep than creep cards. Using inkling is already a smart move, but hoolahoop priestess or wraithling swarm are also very effective (with a nocturne on board) to generate loads of creep, and also useful even without nocturne.
I think the deck goes too big too much. Six 6 mana minions are too much. And what the hell is Nekomata doing there? You’re kinda making Creep/Swarm/Big Abyss/ Dying wish deck with no swarm wincon (which is rather good to include). I would make your hybridisation much more modest by going:
+2 Grimoire (or DFC)
+3 Shadow dancer OR +3 Desolator
+1 Rite (it’s rather easy to find will all that cycle if needed)
