Ive got a list of things that I think will help you build the deck, and which have a very good chance of inclusion
1 Green-Blue-Red Temur The most colorful color combination, green-blue-red Commander decks for Treascures focus on making as many Treasures as possible while allowing you to cast huge creatures early or focus on synergy with artifacts
Sporoloth Ancient and Sporesower ThallidIndividually are kind of slow but not threats so they sneak under the radar
As a result, Firion, Swordmaster (Sram, Senior Edificer) looks great and is a strong early pick
Just like Modern Living End, our primary plan for filling the graveyard is cycling
Commander / EDH / Theme/Gimmick MTG Decks a usually casual deck designed around a unifying theme or idea, such as a single artist or only -cost spells
