Is Debtor's Knell worth it anymore? In the old T2 it was ridiculous because everyone was doing tricks with it + Miren, but it feels sub-par versus a large portion of the field.
Do you really need 4 Wrath of God? I'd think that some of those slots can be best used by running Faith's Fetters; you can get two in by cutting the Void and a Wrath of God; and it doesn't significantly weaken your aggro matchup.
Is Angel of Despair good? I get that it's cheaper than Akroma and it 187s something, but it just seems significantly worse than just bringing Akroma into play, since it's tragically easy to kill by comparison.
Oh god yes Debtors' Knell is the bees fucking knees. If resolved, Knell completely wipes Flare and control decks out. It's still a huge mana investment which is why we weren't nuts about adding more than one, but it's awesome as a one-of.
Wrath of God is easily on the top 5 cards in current standard. I just can't imagine playing less than 4 in any deck running white and having so few relevant creatures.
Angel of Despair is quite good, killing any annoying permanents (Glare, P. Arena, Vitu-Ghazi, etc.) along with assholes like Spectral Force without me having to waste more removal on it. Basically it goes along with the plan of the deck to crush any and all things relevant. Besides, who cares if Angel dies? You run Firemane Angel, which is going to keep coming back over and over again until they get into Demonfire range. Akroma just doesn't strike me as all that awesome when there's about 50 opposing copies of her running around along with specific stuff like Glare and such.
However it's really not that big a deal, if you want to run Akroma, that's cool. We've just had better success with Angel of Despair.
