BT16 Ver. E includes adds additional cards in the following rarities; 2 RRRs, 4 RRs, 8 Rs, 28 Cs, 2 SPs and 4 Legion Rares. Based on promotional images the two new Triple Rares are inferred to be MBT01's Bluish Flame Liberator Prominence Glare and MTD01's Daunting Deleter Woksis, and the new RRs would include Prominence Core's Legion Mate Liberator of Destiny Aglovale. The Sneak Preview prerelease event for BT16 ver. E will feature a playmat with Prominence Core and Aglovale's Legion as its artwork, while the set will feature Thing Saver Dragon and Blaster Blade Liberator. The promotional cards for the prerelease are stated to be Dark Irregulars units, suggesting them to be the Legion pair Psychicers Hadar and Izaya.
The increased set size may prove problematic, as each box is still to contain just 30 packs, and the drastically increased size will make it more difficult to acquire a playset of each rarity. The situation recalls English Vanguard's early infamous releases, which added several Rares to BT03, BT06 and BT04. The addition of just two cards to the Eclipse of Illusionary Shadows caused Blaster Dark to become a $16 Rare for a brief time, and even today the card hovers between $6 and $8. The decision to include Harmonics Messiah in the set was likely done to move the game closer to a simultaneous worldwide release schedule, which Bushiroad has been discussing since Anime Expo 2013.
VGE-BT16: Legion of Dragons & Blades ver. E will be released worldwide on December 19th 2014, six days before the Christmas holiday. The set will include 144 types of cards (RRR: 10 / RR: 16 / R: 30 / C: 88) with 14 Special Parallel prints and 6 Legion Rares.
