The activated mana abilities are like other activated abilities in most ways, and there is no reason that Karn's ability would not affect them. So you are correct, Karn, the Great Creator and Mycosynth Lattice together prevent your opponents from activating any mana abilities.

Modern Tron, or Urzatron, is a deck that runs off of the three "Urza" lands (Urza's Mine, Urza's Power Plant and Urza's Tower) in order to make large amounts of mana. RG Tron, once the most popular archetype, is a Green-based Urzatron deck that frequently splashed for Red in order to gain removal.
Teferi sacrificed his Planeswalker spark, using its energy to close one of the temporal storms. Dominaria survived, but Zhalfir was lost outside of time, and Teferi was left as a powerful but merely mortal mage.
Karna was neither a bad or a good guy in the Mahabharata, he was plain evil and there are several instances in Mahabharat that proves his evil mentality.
Urza was a planeswalker originating from Terisiare on Dominaria, best known for his millennia-long struggle with Yawgmoth and the plane of Phyrexia.
After losing a battle against Nicol Bolas, Teferi gave up his powers as a planeswalker to seal the time rift over Shiv, restoring the continent to its rightful form. Unbeknownst to Teferi, Jhoira wore an amulet around her neck, which contained a small Powerstone holding his Planeswalker spark.
The Mending. Teferi's presence would forever change Venser's life, as the planeswalker's interest in both Venser's latent spark and his ambulator would set off a chain reaction in the Stronghold Rift. Venser was pulled into it along with the rest of Teferi's companions: Jhoira, Radha, and their guards.
Karn is not an artifact, he is just a Planeswalker. He's colorless the same way the Eldrazi legends such as Emrakul, the Aeons Torn are.
Karna had 8 ratni body structure so he had a height of 6''4'' .
