Sideboard questions for kikipod

[Prplprince]

Hey guys and gals I have two questions for my pods sideboard.

1. Is it worth putting  {Agent of Erebos} in there for graveyard hate?

2. Is  {Eidolon of Rhetoric} a good replacement to hate on storm instead of  {Ethersworn Canonist}

Yeah I've got tasty ooze so you're right needed blaack mana would bog it down for no reason

And sweet thanks. I was thinking maybe the 2 Cmc is a bit more useful but avoiding blots could be more imports t
