Lorwyn Eclipsed Part 2: Designing the Lorwyn-Shadowmoor Mashup

Continuation of the Lorwyn Eclipsed Vision Design handoff, detailing how the Lorwyn-Shadowmoor mashup would work: double-faced cards, a rainbow color-matter mechanic, and a mix of typal, hybrid, and non-typal archetypes. It covers diverse DFC experiments (and why seven were kept), cycles such as Behold spells, Reuniters, Changelings, Elemental Incarnations, and rare MDFCs, plus set structure constraints (no common dual lands, hybrid mana fixing, and color-splash limits). The document also lists intended archetypes by color pair, notes content that was cut or deferred, and closes with thanks and a setup for Part 3.
