Renown has three areas you can play around with in design
One of these will be shockingly good in Standard, to my chagrin, but Ive got serious doubts about some seemingly popular cards like: Dragonhawk, Fate's Tempest Eluge, the Shoreless Sea Glarb, Calamity's Augur Helga, Skittish Seer Hugs, Grisly Guardian Mabel, Heir to Cragflame Muerra, Trash Tactician Vren, the Relentless Wick, the Whorled Mind So yeah, most of the story arc cast is underwhelming
Cubing On While Commander Legends: Battle for Baldurs Gate is, unsurprisingly, primarily good for Commander, theres still a lot to like from the set for non-Commander Cubes
As we all know, card-advantage is king in Commander
Using flashback still limits the card to its original casting speed
