Generally, these are super cool but I have a few nitpicks:

• Pinnacle shouldn't have the :. It's not on Overload or Kicker.
• The Legendary Dragons feel too similar to each other to be mythic. I'd make them rare or have flashier abilities.
• The legendary lands feel similar, and uncounterable isn't in black and white mechanically, so that's a color break. Maybe just "Your COLOR spells can't be countered while this is untapped."
• Tapped out doesn't work period because you can just initially tap all of your lands even if you're not using its mana to cast something. I guess it doesn't work with counterspells, though.
• Parasite Beetle is weird enough to be mythic
• Krakatuo is impossible to track because you generally don't know how many cards are in your library at any time. Also, it's broken and i'm pretty sure the text is wrong.
• The uncommon land cycle should be 2, T: You gain 1 life. Also, it seems bad.
• Geographical Anomaly should be Pay 1 life, T:. Also, remove the second ability. It gives Anomaly "T: Add G", "T: Add B", etc
• The basic lands are missing the big emblem thing.
• Payed should be paid.
• You should probably get rid of the random kicker card because it has mechanical overlap with pinnacle
