That's pretty excellent value. A 2-for-1 that hits a creature and sets your opponent back a turn is still solid, especially if you went first.
Heck 3 will be rare even already as enchantment/planeswalker don't feature together with creatures all too often either, 9 out of 10 times this will be a "2 for 1" I bet.
"2 for 1" i say because killing a land is rarely relevant by the time you play this.
As it is this card is pretty bad. 6 mana cards need to provide much more reliable real 2 for 1s.
