Here is an explanation of the changes from Magic R&D:

Gush
Gush was one of the best card-drawing cards in the Standard format during 
its run; it should be no surprise that it has become one of the best 
card-drawing cards in Type 1. Gush's alternative play cost often results 
in players gaining mana, in addition to the two cards drawn.

Mind's Desire
Although we prefer for a new card to be "proven" in a format before we ban
or restrict it, testing has shown that multiple copies of this Scourge card 
can quickly lead to degenerate game states. With four copies of 
Mind's Desire, a player would be able to play every card in his or her deck
on the same turn without too much difficulty.
