Hare Apparent is a Rabbit that allows a deck to contain any number of copies of it, ignoring Magic's normal copy limits. Each one creates Rabbit tokens when it enters based on how many other Hare Apparents you already control, allowing later copies to produce increasingly large colonies.
Anointed Procession can double the resulting Rabbit tokens, while Valley Questcaller strengthens the growing swarm. Panharmonicon-style effects can also make each Hare Apparent's enter-the-battlefield ability considerably more productive.
