Commander 2020: IKO Symbiotic Swarm

Ikoria: Lair of Behemoths makes use of monster movie tropes, and is especially inspired by Kaiju (a Japanese genre of films featuring giant monsters like Godzilla).

The setting is Ikoria, a plane of beasts and monsters.[13] As the world of Ikoria developed, humans quickly realized what types of defenses were needed to stave off monsters. The humans were quick to become both militaristic and ingenious. Unfortunately for the humans, the monsters of Ikoria have begun to mutate and the fortresses that were previously successful at protecting humans have now become fodder for the monsters to annihilate. Featured planeswalkers are Vivien Reid, Lukka and Narset.
