Zaida Toniwan

Delirium — Zaida Toniwan enters the battlefield tapped unless there are four or more card types
among cards in your graveyard.
Whenever Zaida Toniwan blocks or is blocked,
you may exile it, then return it to the battlefield
at the beginning of the next end step.
While discretion is the better part of valor, laziness
can also do in a pinch.
