The other day, as I was working on an Ashnod, Flesh Mechanist deck for EDH, I wanted a Culling the Weak, but my three copies already had homes in other decks
Clone with flash is about as good as copy-creature effects get, and while thats a crowded category of cards, Stunt Double always does good work
So much so, that it started causing some problems, which I will now walk through
When you do, however, Dig Deep can get you closer to your game win while amassing a powerful board that your opponents are forced to deal with
As an additional impact, whenever you cast a small noncreature spell (mana value 3 or greater), Yshtola deals 2 damage to each opponent, and you gain two life
In a sense, Frog is a cost-reducer for your most important card, and win condition, while also serving as a draw engine
