mtg jodah commander deck EDH Deck Jodah, Archmage Eternal 100 Magic Cards Custom Deck 5 Color exile cards from the top of your library until you exile a legendary nonland card with lesser mana value Jodah, the Unifier Legendary Creatures

You can drop this on turn three, sacrifice a two-drop artifact dork for two cards and two mills, sac it to Goblin Welder to swap for something you just milled or what you sacrificed, and then swap the sacrificed or milled card on turn four for this to keep

Regarding cards that are restricted other than banned, they are only applicable in a select few formats where players are only allowed one copy of the card in their main deck and sideboard

If both permanents are on the battlefield, both will trigger separately, allowing you to essentially double up on the effects that get triggered
