I find this game has two major ratios, and then some minor ones dictated by a given world or attribute's unique needs. Those two major ratios are dictated mostly by the deck's playstyle... Control decks have a higher ratio of spells to monsters. Beatdown decks have a higher ratio of monsters and items.

Generally speaking, for most decks, I see it beneficial to keep monsters equal to or greater than spells, and impacts + items to 9 or 10 cards. A standard beatdown deck built by me tends to look like this:

Monsters - 23

Spells - 18

Items - 6

Impacts - 3

The standard Control deck will usually end up looking like:

Monsters - 20

Spells - 20 (21 in 72 Pillars)

Items - 4-6 (Leftover usually floods into spells or monsters; these also don't have to be included except by the fighter's preference.)

Impacts - 3-4
