I don't think field consistency affects much in buddyfight. You're assuming that a field of 3 size 1s and a field of 1 size 3 will function the same, when in reality they don't.

What should affect your ratio choice is not how often you have a size 3 field, but instead a range of other factors like gauge usage, card advantage vs field advantage (eg it takes less cards to make a full field using a size 3, but you also lose that full field with only 1 monster destruction), item usage, special circumstances such as Gargantua Punisher, etc.

Also, what world you are using has a huge impact on your monster ratio. Worlds with weaker monsters (Magic World) benefit more from other types of cards like spells while worlds with stronger monsters (Danger World) benefit more from an increased number of monsters due to having a size 3 field being more significant in decks with stronger monsters.

Playstyle is another big one. A player who likes items should not have too many size 1s. A player who likes impacts should not have too many size 3s. These are just 2 examples, but there are many more.

Buddyfight is not a game where you can apply a deck ratio to every deck. Different decks should stick to different ratios. Also, different players should stick to different ratios.
