There are several combos here, mainly, decimating
Reap with
Silvercrest Purifier out, or dropping
Memento Mori. Of course, Severin is here too.
From Beyond is here to hit early removal or threats that might kill you faster or interrupt your gameplan of OTK with Purifier, mostly things like Desert Marshal, Milos, Sear, etc.
Maeve, Walker of Aeons can put your graveyard back in your library with greater value, especially
Piercing Grief
Cull the Deck helps you dig or just general card advantage.
Porcelain Mask is to silence problem units and more importantly, give Overwhelm to
Silvercrest Purifier!
Display of Vision, and
Bartholo's Keepsake has been great for ramping and digging.
Harsh Rule is to clean up if you aren't getting anywhere, or switch gears if the game goes too long.
Severin of the Dark plays well with Reap and
Memento Mori
Power base has been under scrutiny for a while but I think I have figured it out.
Protect helps save your units, or yourself from removal/curses.
Annihilate is largely here against Milos, but of course it is a great removal card.
Saber-Tooth Prideleader Relic removal, surprise blocker, DO NOT BLOCK MILOS WITH THIS.
The market is constantly going through changes and market access as well. I feel like
Shen-Ra Speaks is necessary, and I really like Silent Hysteria .
Crack the Earth makes a chump blocker and gives us additional market access but isn't the primary market focus,
Ebon Dune Smuggler has been great and I think not locking ourselves into 5 drops only is important. I have moved Memento Mori to the main deck, and I think it is better for our odds of combo-ing, and being able to market for answers instead of a combo piece has better reliability.
This deck feels more like a MTG deck than anything I have played in eternal so far, disrupt your opponent in the first few turns then combo off in the next few if you are lucky.
Worst case scenario the deck is good for getting your 100 Justice damage in one turn!
