I prefer the way where we say "Turtle Beast" for example, or just find beast art, that fits the flavor, because a supertype is something that leads to high expectations and such, like a lot of cards with that type and maybe a use over more than one set (I mean, there are technically some wild beasts in every set).
You posted before me like always, this time I agree 100%, that should be our reminder text.
I wanna show you guys something else, I'm not sure if it is actually good. I though about a way how to finally implement the alchemist trope into MtG and found that the green-based sultai faction would be prefect for that. My best solution so far is that: Cards create ingredient-tokens. Ingredients are new card types, that only exist as tokens. There are Alchemists and aligned spells in the set, that let you sac 2 or 3 different ingredients for powerful effects. To make it less combo, I gave all of them a small effect if you sac them alone (as in just eat it).
Stinkbug
Ingredient
, sacrifice this ingredient: You gain 1 life.
Gloom Toad
Ingredient
, sacrifice this ingredient: Scry 1.
Skyleaf
Ingredient
, Sacrifice this ingredient: Target creature gains flying until end of turn.
Bloodberry
Ingredient
, sacrifice this ingredient: Untap target creature.
Something like this, I think 4 would the highest number one set could allow for one mechanic. Obviously, the tokens would come from cards in colors, that allow the effect.

At the beginning of your upkeep create your choice of a Gloom Toad ingredient token with "

Their best use though, would be with other alchemy-related cards.
