Dillon Deveney, the set's creative lead, happily approved most of the suggestions
You can get some pretty sweet, limited edition skins, though - for example, if you bought the 'Warhammer Bundle' during the October 2023 Warhammer 40k Secret Lair, you got two codes, each good for ten premium card sleeves showing the 40k-ified versions of classic cards: Merciless Executioner as "Ork Kommando" Aggravated Assault Krenko, Tin Street Kingpin as "Makari the Lucky Grot" Zurgo Helmsmasher as "Ghazghkull, Prophet of the Waaagh!" Blind Obedience Danitha Capashen, Paragon as "Neave Blacktalon" Najeela, the Blade-Blossom as "Archaeon the Everchosen" Scourge of the Throne as "Stardrake" Beware, though - this is often the priciest way to find new codes
Given how this can come out of nowhere to change your combat math and you can cycle it in the early game when you need to, Id be happy with Hill Gigas in most red decks
Once we complete the dungeon one time, our dungeon creatures (Caves of Chaos Adventurer, Ravenloft Adventurer, and Tomb of Horrors Adventurer) become that much more powerful, and with Loot Dispute out, we get a 5/5 Dragon whenever we complete the dungeon
Commander Legends: Battle for Baldurs Gate gave us some spicy new ones as well, like the three Elder Dragons (in our colors), Ancient Bronze Dragon, Ancient Copper Dragon, and Ancient Silver Dragon
