Oracle Text: Legendary Creature - Human Warrior Dakkon Blackblade’s power and toughness are each equal to the number of lands you control. Scryfall: scryfall.com/card/leg/225/dakkon-blackblade
Dreamscape Artist is blue because it’s originally from Planar Chaos. The theme of that set was “what if the color pie had got this way instead of that way”.
There's a lot of really cool looks at colorshifted cards in thst set. Damnation exists because it is a color shifted Wrath of God. Pyrohemia is a color shifted Pestilence
I like the way that instead of big commander = combat only, you found a couple other ways to kind of abuse him. For extra land drops, deep gnome terramancer is a great card to consider! Anyways great build!
I decided to not run deep gnome terramancer because I’d rather be more in control of the ramp and I still run archaeomamcers map because it draws lands. I could see depending on your pod how deep gnome could be cracked though.
