Commander and Starter decks are currently the only official preconstructed products, and they usually release alongside each game expansion
In Unstable we had the card Earl of Squirrels, which had the Squirrellink keyword to make Squirrel tokens whenever it dealt damage to a player, and the artifact Steel Squirrel, while Unsanctioned had the Half-Squirrel, Half- augmented creature, Snickering Squirrel, and the squirrel Commander Acornelia, Fashionable Filcher who made acorn counters whenever a card you cast had a squirrel in the art
If the population of the card is low, its price could easily jump above the $1,000 price point before long, and maybe even surpass that of the current Kevin Eastman Headline Signature Turtle card benchmark of $1,500

Sliver Gravemother also works super well with a couple new Slivers too
