Is this a strictly better version than Time Reversal from M12/M11?
each player shuffles his or her hand and graveyard into his or her library, then draws seven cards. if it's your turn, end the turn. (exile all spells and abilities on the stack, including this card. discard down to your maximum hand size. damage wears off, and "this turn" and "until end of turn" effects end.)
You can cast this card for cheaper but the big issue is that your opponent will be able to use the cards he draws before you do, unless you cast it at the end of their turn. Strictly better, I'd say no.
