mtg roon of the hidden realm commander deck EDH tech for A single individual card from the Magic Roon of the Hidden Realm

The downside of this eldrazi commander is that, unlike its older version, it has no way to defend itself, and there are plenty of colored eldrazi that would be a great fit here but you cant play due to the color identity

This includes mana rocks, of which there are nine, Spawn/Scion makers (eight), cost reducers (four), and even a mana creature (Snapping VoidcrawSnapping Voidcraw), a card that steals lands (Oblivion SowerOblivion Sower) and a mana increaser (Forsaken MonumentForsaken Monument)

It grows your dork and then has hexproof to shut down targeted removal too

Planar Genesis Though simple, Planar Genesis is quite the potent card

Cards like Agent of Masks, Blind Hunter, Ghost Council of Orzhova, Mourning Thrull, Orzhov Guildmage, and Pillory of the Sleepless all bled your opponent to death, draining one life point at a time (well, two in the case of Blind Hunter)
