This update follows an attempt to improve the quality of decks for tribal-based synergies, Elementals in Temur, Blex stuff in Golgari, and added full support for Sultai to have a Morph archetype.
Changes listed on this update are not one-to-one in terms of this card was chosen over this card, but rather just organization to make the update easier for me to process.
This is the first draft of changes. Once submitted, a follow up audit will make additional changes.
