Help me find a commander that matches my DnD character!

My friends all play both mtg and DND together, and we've started building decks themed around our PCs in our campaign

For example, one of us plays a Mousefolk who wields a legendary weapon, so she built [Mabel, heir to craigflame]]. Another one of us plays a Plasmoid cowboy so they built [[Felix Five Boots]].

My character is a Human Artificer that carries around a massive buster-blae esque sword that "eats" material like magic items, plants, or other raw materials, and converts them into magical swings of his sword matching that element. So stuff some hot coals in there, boom fire damage.

I'm thinking if there is some sort of human artificer commander that relates to 5 color and equipment maybe? Or one that wields a big sword or is voltron?
