Silence is one of the best parts of TES.
With cutting Rainbow lands and Rite of flame you lose the fast Thing for TES.
For playing Artifacts Land, you lose the concistant thing of ANT.

that seems very bad.

Mox Opal is not better with the Lands. You Need 3 Artifacts and you haven't them all the time..

Rite of Flame give you +2 or more red mana. Mox Opal not...
Rite of Flame allowed you to Play 4 BW.
BW whitout rite of flame seems bad...that meens you lose again concistants.
