Covenant of BloodFirst, huge disclaimer: I don't have the whole card pool which explains some of the bizarre card numbers (I need more
Lone Missionaries obviously).
Some of the changes:
Reprisal over Ulcerate - with 4/4 Angels and 0/4 Walls, the only things that can really become problematic are things with 4 or greater power. It's cheap, instant removal of these things.
No Ordeal of Heliod - I need things that want to attack to get use of this. Great combo with Pridemate, but most of the other things in the deck aren't really attacking much outside the really early game. I put Meditation Puzzle in its place, which should always be "Deal 8 damage to target player and gain 8 life," since you should never unload it without Vizkopa or Sanguine Bond around. Gets really silly with Faithmenders out, and is instant speed, so you can end-phase Convoke it out before your turn for essentially no cost.
Elixir of Immortality is another instant-speed way to engage the burn off Vizkopa and Sanguine, or get an Angel if you really want. They're so cheap.
Lastly, yeah, Covenant of Blood is weird. Might kick it out, but also becomes a solid finisher once you're setup with Vizkopa/Sanguine, it's kind like
Corrupt. It's terrible removal in a pinch as well.
But as mentioned, I don't have all the cards, so changes will come as I get my final Missionaries and Guildmage, among other things. I like it though, sometimes I don't even swing in with anything. Needs to get Angelic Accord/Sanguine/Vizkopa to win, and just unload the saved up healing after that.
