A lot of these aftermath cards play out in combinations, where the first effect complements the second, but both are useful on their own. This one is just two different acceleration effects strapped together, with no synergy. Shame they couldn't get more creative with it, like:
Spring 1GG
Sorcery
Draw a card for each untapped land you control.
//
Mind 1UU
Sorcery
Draw a card for each card you've drawn this turn.
