Creating creatures that can go into combat is great, however, using them for Waterbending is mostly a secondary thing
That one's currently a Game Changer in Commander, but Braids, Arisen Nightmare isnt and can prove to be a fun little card
The only reason this didnt take the #1 slot was the lack of a save feature and the handful of missing frames
Its probably a coincidence that many of the main FFVII characters get the most busted cards from the set, whether from the Commander set or the Standard one
At the same time, the Hero deck required fewer lands, which meant that the Rat deck was more likely to get mana flooded (by virtue of needing to build with more lands in the deck)
This evens out the playing field, replacing large Voltron creatures or aristocratic life drainers with manageable small tokens instead
