A deck that focuses on triggering Angelic Accord as much as possible and swooping in with an army of Angels. I'll go through the purpose of the cards one by one.

Angelic Accord - The bread and butter of the deck. No explanation needed here.

Bubbling Cauldron is the main reason for an Angelic Accord's Trigger. Coupling with Bogbrew Witch and Festering Newt is a no brainer. It quadruples the newt's strength and take 4 life from the opponent. What else could you ask for?

Trading Post is there for its flexibility. Discarding a card for 4 life sounds horrible, but think of it as a 1 mana cost angel. Pretty good IMO. If a Bubbling Cauldron gets sacked, Trading Post can save it. Extra Bubbling Cauldron or Trading Post? Trade them in for a draw card.

Drainpipe Vermin is another creature to be sacrificed into Bubbling Cauldron. It works as a control of a sort.

Elixir of Immortality helps in triggering Angelic Accord, but more importantly, recycle Festering Newt which can be bought back by Bogbrew Witch.

Tenacious Dead can be used as a blocker or another sacrifice for Bubbling Cauldron. A mana sink because you wont be needing them that much.

Pacifism, a cheap removal. Not much to add.

I have considered putting in Dark Prophecy in place of Drainpipe Vermin or Pacifism to get card advantage.

Let me know what do you think of this. I try to make it budget friendly, as that is why its missing shock lands and what nots.
