Well, due to changes in the metagame (and rotation), Charizard ex has switched to a Noctowl [Stellar Crown] engine to search out whatever it needs, and dont worry, Pidgeot ex [Obsidian Flames] is still included in here too
Rare Dual Lands I dont have much to say about these lands that Naomi Krause didnt already cover in her set review for Midnight Hunt
Those are just a few of the most explosive options
Fighting-types may have raw power, but Fire can turn the heat on early in the game
Marina Vendrell is a 5-color commander that allows you to look at the top seven cards and put all enchantments in your hand, so thats a nice card advantage engine
Your Commander must be a single legendary creature, although two cards can be used as dual commanders if they both have the Partner ability
