In general, when making the cuts and inclusions, I tried to prioritize cards that I considered more interesting and cut the most generic effects – even in their most powerful versions. It wasn't always possible, however, as the multicolor pool, especially for enemy pairs, is pretty shallow. Spectral Lynx, Life //Death and Aether Mutation are examples of these less interesting additions – but I hope they'll be effective nonetheless.
One of my all-time favorite cards. Included in the hope that it will facilitate the emergence of UB Midrange decks that look to reuse ETBs to generate value.
Included as an efficient and hard-to-remove beater. WG can be as fair as possible, but I also want it to be deeply resilient.
The only 3-color card in the cube is another pet card of mine. There's not much else behind the reason for the inclusion. It is noteworthy, however, that it occupies a place that would have been assigned to a card because Jilt was included as a blue card.
This inclusion is a test. Introduced thinking about stimulating a micro synergy with auras and in the midst of a color combination that has many wraths. I'm not sure what to expect actually, but it seemed like a more interesting addition than the rest of the cards in the pool.
One of the things this update tries to solve is to establish a better balance between allied and enemy color pairs. Therefore, some lands specifically geared towards allied pairs were cut in favor of the Lairs from Invasion. Besides that, some Rainbow and Utility lands were included to compensate for the increased number of cards in the cube.
As for the artifacts, in addition to the remaining diamonds, Aeolipile and Serrated Arrows were included as removals to compensate for the increase in the number of cards in the cube. In addition, I removed the custom Ashnod's Battlegear and included Power Matrix, another card that probably should have already been included a long time ago.
