Varchild, Betrayer of Kjeldor could be fun in some sort of group slug deck where you give your opponent tokens but in a harmful manner (maybe with something like Trespasser's Curse on the battlefield), although she might be better in the 99, since mono-red is pretty limiting
If you can snag a Pirates Cutlass, or any kind of Equipment really, it can really do some work over the course of a game
This combines well with Mutate cards such as Cavern Whisperer and Chittering Harvester
Through her passive ability, she can immediately begin producing Warriors while threatening additional combat phases later in the game with her activated ability
Even the flavor text makes a direct reference to the maw
This is mostly to avoid the look of impropriety, as being able to see the back of the card means theres the possibility of marking (i.e., putting marks on certain cards so you can tell when they pop up in your deck without drawing/scrying them)
