This deck seems to be trying to do all of the above out of the box
The decks will each contain 62 new cards designed specifically for the multiplayer mode, and restricting them from use in standard play due to their increased power, as indicated by a new label at the bottom of each card
Anyone that was wanting a little more complexity in Lorcana will be able to find it now in Rise of the Floodborn
Plus, running a mono-colored Commander presents its own challenges when it comes to deckbuilding
That being said, buying key cards at the bottom was a strong move in isolation, since 14 of 15 mythics have appreciated at least 10% from that point, with eight of those cards appreciating as much as 75% (LOTV, Cavern of Souls, Snapcaster Mage, Craterhoof Behemoth, Temporal Mastery, Olivia Voldaren, Past in Flames)
That in itself is a huge boon in Commander games
