The blade seems pretty fantastic to me as it removes the need to pack in 3+ "swords of X and Y" to ensure that you can get some sort of protection... even if it isn't as encompassing.
I hope that the presence of flawless maneuvers means that we're getting a full cycle of these free tricks. While the fog seems a bit better defensively (as it stops unblocked creatures from smashing your face), the ability to blank removals or throw this down for free before slamming a sweeper is *chef kiss*
Holy crap, Molten Echoes is pure infinite combo fuel. Yes it's sweet in pretty much anything Tribal but I wouldn't be surprised if I saw it naming Cat at least once.
Flawless Maneuver is also a homerun. It's not White card draw nor ramp, but it does helps White a lot against wraths, which often is its biggest enemy. Still won't save you against Terminus or the likes, but it's a step on the right direction.
Sword is cute. It's an useful tool for Voltron strategies, I guess?
