I'd say that this card should have its cost increased by 1 upped and unupped, or something like that. Precognition is used in some rush decks with a splashed time mark, (although that's not so effective), and I would guess a majority of time rush decks would use precog. This is because it effectively reduces the amount of cards in your deck by 1, making it slightly faster. This card, in a mono, would do the same but better (minus the viewing of the opponent's hand). Pretty much, with this card as it is, the upped version can be used in any mono deck to speed it up slightly. It would also be really effective in a lava golem deck, as was mentioned before. 6x lava destroyer, 6x cremate, 6x RoL, 6x burning flash, possibly some earthen flashes, and some creature control or something like that. I'm sure that's not the best it can be, but it makes a golem rush more powerful that it already is. And for any mono deck, it can make it have 1 less card, as i previously stated. I'd say don't make an upped version that can pay for itself, either make it 5 unupped/4 upped or 4 and no draw unupped and 4 and draw upped. something like that.
