Rendmaw, Creaking Nest is a Legendary Artifact Creature — Scarecrow (mana cost {3}{B}{G}; 5/5; rarity: mythic; most recent printing listed by Scryfall: Duskmourn: House of Horror Commander). Its colour identity is black, green, 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 Rendmaw, Creaking Nest does
The card's exact text is where every honest build starts:
Reach, menace
When Rendmaw enters and whenever you play a card with two or more card types, each player creates a tapped 2/2 black Bird creature token with flying. The tokens are goaded for the rest of the game. (They attack each combat if able and attack a player other than you if able.)
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
The wins rarely come from a single spectacular play. They come from the deck doing its ordinary thing one turn earlier than the table expects, then doing it again while opponents are still setting up. Build for that ordinary game first: enough lands to make your drops, enough ramp to reach your key spells on schedule, and enough card flow that one removal spell slows you down instead of ending you. Protect the turns where the commander connects its text to the board — those are the turns the whole list exists to create.
If this topic is on your bench, keep going with Kenrith, the Returned King Commander Guide: How the Deck Actually Wins — it covers the neighbouring decisions from a different angle, and the two pieces together give you a fuller picture than either one alone.
Building and tuning tips
Every slot should argue for itself against the card it replaced. Test a new inclusion through the deck's normal sequence — early development, mid-game pressure, late-game closing — and notice where it helps and where it sits dead. Cards that only shine in the best case are the first cuts when a proven role-player needs the slot back.
Keep the mana honest, too. A commander in black, green 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.
