An old 'classic' Deck I built back in the day before there was Expedition. Nowadays there's plenty of options in the cardpool to change it around with potentially better combos. Still does well in Master Gauntlet, so maybe someone'd like to give it a try.
The HotP, Ghostblade and Crownwatch Pressgang are essentially the keycards, other cards could be replaced with similar-cost equivalents without loss of consistency, and even potential increase in Winrate. Still would strongly advice to keep Immortalize and either Grief or Alchemist in.
Specifically the Aegis Support, which back then was monumental, since alot of removal focus, especially in Red, would otherwise stomp this deck. It is safer, but slower, to play the HotP only if you have the mana to at least play Ghostblade with it, however, interactions where you play the HotP explicitly to soak up a removal are often viable, especially if you have the mana to use a revival.
This deck is build to function continuously with only 3 mana, hence the low mana support, even a prolonged period of only 2 Mana can work out. Of course the mid term required ceiling is 4, while the desired long term ceiling is 5, at which point one should liberally decimate. 5 is desired for utilization of Cabal and Crownwatch Tactics. In a last ditch effort, do not neglect the Nihil Draconus added to your void by fell ritual. Specifically when ending the turn with 2/5 Mana and Immortalize in hand, it is worth to consideration, also with decimate, as the draconus is a 4-cost 5-5.
