This bizarre interaction arises when Clever Impersonator enters the battlefield as a copy of Garruk Relentless // Garruk, the Veil-Cursed, retaining the planeswalker's copied abilities but lacking a crucial rule built into double-faced cards. Because Clever Impersonator is a standard single-faced card, it completely fails to transform when its loyalty drops to two or fewer from using Garruk Relentless // Garruk, the Veil-Cursed's damage-dealing ability. This leaves the game stuck in a mandatory loop as the game state constantly attempts to transform a permanent that physically cannot do so, inevitably resulting in a draw.
