It doesn't give you additional Saprolings if more than one creature died
These decks are built so that most or all of their creatures share the same type so an all-elves deck, or all-squirrels, or all-ridiculously-adorable-floppy-rabbits-with-ridiculous-floppy-hats
Including 6-9 Commons, 3-6 Uncommon Cards, 1-4 Rare or higher, and 1 Land card (20% chance of a traditional foil and a 1% chance of bagging a Foil Boarderless Mythic Rare)
Plus, both decks can use it to randomly hose Burn or Mill decks, which really struggle to win when they can't target the opponent with their spells
Players begin by selecting one of the several pre-made decks, or by building their own
