I'd choose Never. It gives you additional advantage as early as 4 mana. While Ruinous has a big upside, you can't get access to that until 7 mana, so the "installment" payment of the Aftermath suggests to me that it's more likely to be cast. Return can also be useful in a GY hate scenario.

You can't play Hero's Downfall in Frontier.
I prefer something more direct than To the Slaughter.
I have Anguished Unmaking, as well.

Although, if your SB has 2 or more slots dedicated to PW hate, you could always put one of each...?
