I cloned this from the 100 Ornithopters Cube. I intend to make a Twobert from this cube, hence 50 Ornithopters.
Below is their helpful primer:
A perfectly normal Cube with one twist: the only creatures are 100 copies of the card Ornithopter. There are no creature tokens, there are no creature lands, and there are no win conditions that don't have something to do with the card Ornithopter. Inspired by a tweet and featured at CubeCon 2024.
