Rite of Consumption For the combo payoff

…or Apostle's Blessing

Dead_Blue_ I definitely think Apostle's Blessing is a strong choice, especially as a sideboard option against Chalice of the Void to swap out Disciple of the Vault, and it has the added benefit of being especially strong in the current multicolor-piled meta. I don't know that I quite understand Rite of Consumption, though. I get the idea behind suggesting it, but in most cases I'd much rather have a main-field body like Disciple of the Vault or Zulaport Cutthroat that acts as a latent combo piece until the last piece resolves than a sorcery-speed payoff.

I've added both to the maybeboard. I'll likely put Apostle's Blessing in the sideboard (possibly over the mana-intensive Murderous Rider).

Thank you for the suggestions!
