You can already see the next card (and any other cards) your opponent draws on the turn you play precognition; the opponent's hand is visible for your turn and the AIs next turn. I like the idea of the upgraded card giving you a free draw, but I think you should find a different effect than 'view top card of deck'. Perhaps you should have it so you see your OWN top card, or top 2-3 cards? That would make it functionally different than precognition; as the card stands now it is basically the same as precognotion.
Hrm...Maybe this could be a permanent? Entropy is kinda missing one, and it would explain the higher cost...Though I feel like this card kinda needs an expanison on what it's supposed to do.
