Ive also seen some Jund builds floating around that cut Bloodbraid Elf and Liliana of the Veil in favor of Dark Confidant, Mishras Bauble, and Kroxa in order to enable Lurrus
Plus, Im also not a big fan of playing cards from exile cards that Wizards of the Coast (WotC) has been pushing lately, at least not in Commander
At the beginning of your combat phase, Blitzwing, Adaptive Assailant gets either Flying (like a plane) or Indestructible (somewhat like a tank) so that it can swing in for some damage
Titania, Protector of Argoth Titania, Protector of Argoth allows you to lessen the sting of sacrificing your own lands
While in RTR the truly awful cards were Aquus Steed, Chronic Flooding, Destroy the Evidence, Drainpipe Vermin, Shrieking Affliction, Sphere of Safety, Survey the Wreckage, Oak Street Innkeeper, and Urban Burgeoning, with only five of those at common, GTC presents us such gems as Hydroform, Primal Visitation, Guildscorn Ward, Contaminated Ground, Dying Wish, Illness in the Ranks, Mental Vapors, Crackling Perimeter, Structural Collapse, Tin Street Market, Furious Resistance (no, it is not a red Smite, people!), Alpha Authority, Predator's Rapport, Serene Remembrance, Coerced Confession, and Skyblinder Staff
