Chaos in Tavmir

The Rundown

Chaos in Tavmir is a custom set about a plane created by two powerful planeswalkers: Renaut Zul and Nicol Bolas. It was intended to spite Zendikar after the Eldrazi failed to destroy it completely. But now, humans and angels are trying to cleanse the plane, as it corrupts the entire multiverse. After learning this, Renaut and Bolas strengthen the plane, causing it to rapidly grow. Will you assist the Hellwings or the Purifiers?

If you would like to help with the set, private message me, and I will most likely give you access to the account. But first, some thanks.
