Queen Marchesa is a Legendary Creature — Human Assassin (mana cost {1}{R}{W}{B}; Legendary Creature — Human Assassin; 3/3; rarity: rare; most recent printing listed by Scryfall: Outlaws of Thunder Junction Commander). Its colour identity is black, red, white, and its Commander legality on Scryfall is listed as legal. This guide explains what the card actually does, how a deck built around it wins, and which decisions matter most when you build your own version.
What Queen Marchesa does
The card's exact text is where every honest build starts:
Deathtouch, haste
When Queen Marchesa enters, you become the monarch.
At the beginning of your upkeep, if an opponent is the monarch, create a 1/1 black Assassin creature token with deathtouch and haste.
Read that text literally. Every line of it is a building instruction: the abilities tell you which supporting cards multiply the commander, which weaknesses opponents will attack, and which turns of the game the deck is designed to own. Brewers get into trouble when they build the deck they wish the commander were; build the one this text describes.

How the deck wins
Ask what the deck looks like when it is merely fine. A resilient build still develops its board, still draws extra cards, and still threatens something through an average opening hand. The spectacular draws take care of themselves; spend your card choices making the average draw functional, because you will see far more average draws than perfect ones.

Building and tuning tips
Sequencing is a skill this deck rewards. The order you deploy threats, hold interaction, and commit to the board decides more games than any single card choice. Play a few games slowly, talk through your turns out loud, and the deck's real lines of play will surface — then tune the list to serve the lines you actually take.
Keep the mana honest, too. A commander in black, red, white colours needs a mana base built for those colours in the proportions the deck actually casts — a lesson the MTGBrew Learn guides return to often, because no strategy survives a mana base that cannot cast it.
