2/2

Am I crazy to think this wouldve been fine if it read like "Colorless Eldrazi spells you cast with mana value 3 or greater cost {1} less to cast." To avoid reducing itself and other cheap problematic eldrazis but still reducing keycards like Reality Smasher, Thought-knot and Matter reshaper?

Anywho, any way this sees play in modern? Potential to make E-tron go a different direction, or is the 7 mana value too restrictive with to small return?
