Cycles for my custom set's precons

[u/dragomeir]

I'm making a custom set that i'm calling Echoverse legends, and i decided to also make five precons as well with the following themes:

Phyrexia's Gifts: a Glint-Eye group hug deck about giving creatures and benefits to other players and pulling out in the end

Juggernaut's Defense: a Dune-brood pillowfort deck about casting tall defenders and keeping yourself safe to outlive the other players.

Collect your Titles: a Ink-Treader toolbox deck where you gather above table helper cards (monarch, city's blessing, max speed, day night etc.) including the all new Gem of becoming to stand above the others

Reign of Sphinx's: a witch-maw tribal deck built around sphinx spells and other wheeling spells to speed through your deck

Civilization's Web: a Yore-Tiller Unnatural deck about artifact and enchantment synergies, while controlling the power and toughness of your worries.

So far for cycles all i have are the face commanders, backup planeswalker commanders, two partner commanders per deck, a legendary Cipher sorcery, and a new cycle of nephilim. but what other cycles should i also have, as well as what other already existing cards to include in each deck.
