Change log:
Shortened all gym names. Changed all gyms except Flying, Normal, and Steel to ETB tapped to balance the others. No more strictly-better basics. Added filter effects to the duals to weaken them a bit, instead of just "make any color" like the others. Added new mechanic, Move Tutor, to some Tribal Instants and Sorceries. Bumped up a lot of mana costs as many creatures felt much too powerful. Gave "World Enchantment" effects shroud so they couldn't be removed by simple disenchant effects. (They already have Vanishing, you must weather the storm.) Added a type-relevant effect to all the Tribal Enchantments for more synergy and less "Generally good"ness. Added various "Non-type" riders to spells to evoke the Immunity effects from the pokemon games. You can't punch Ghosts, and you can't sicken Steel.
All players now begin the draft with a Town Map and a Pokedex, both for flavor and deck-playability reasons.
