Spoiler: MonoB Devotion
sideboard is just a pile since I haven't really done Bo3 with this deck yet; I blame my recent purchase of Stardew Valley and also the sets been out for like a day [edit] cut the 3x Leylines for another Remorse and 2x Epic Downfall
anyway
4x Knight of the Ebon Legion - so I've seen some early monoB lists going Cat-Combo with the deck, and it's cute but also takes up 8 slots in the deck. wasn't running a one-drop for a while and found that it was just too slow, so it was this or Gutterbones. Gutterbones could be cute with its recursion but the Knight is just too strong a card just on its own.
3x Tymaret, 3x Yarok's Fenlurker - Tymaret is dope and I'd play 4 except you don't want too many copies stuck in your hand while he sits there gaining toughness. the Fenlurker has been medium but the pips kinda help and he usually gets a card off Ayara/Reaper, definitely don't want 4 though.
2x Drag to the Underworld, 4x Murderous Rider - Drag has been medium for me, but you want enough killspells in the deck, and it's usually costing BB which is fine. tempted to cut a Murderous Rider but that's probably wrong. not playing Eat to Extinction only because the 4-drop slot is heavy at the moment.
3x Ayara, 3x Midnight Reaper - in my defense of 3-ofs, some of these are legendary. for Reaper, I just couldn't find a cut to justify a fourth. either way, both of these are great card draw engines and have amazing synergy with our premier 4-drop:
1x Rankle, Master of Prankles - nah jk but this guy is too fun to cut from the 75 and sometimes really pulls his weight. I almost never want to see more than one though and he's easily cuttable in boarding
4x Nightmare Shepard - you had me at 4/4 Flier for 2BB. you can go off with Ayara or just smash in, or both. run four, this guy's great.
2x Erebos - this guy hasn't shown up a lot for me in games for some reason, thanks RNG, but you run at least one, right?
1x Deathless Knight - I don't know if this is good, but I'm trying it. Ayara, Gary, and attacking with our Lifelink Knights can trigger it, good against boardwipes, recurring chumpblocker in some long matchups... 4 pips of devotion, I can't not be tempted.
2x Cavalier of Knight - this deck wants some nice midgame threats and Gary is more of a finisher card here. I've been a fan of this card in certain RB Aggro matchups, and have been satisfied with its performance in the 75 so far here.
3x Gary - not playing four??
blasphemy
. but as much as you want to see Gary every game, I've won a few games without him, some games you lose because they can deal with your devotion and then you're just playing a 2/4, and you have enough card draw in the deck to see one per game. obviously two is gravy.25 Land, 3x Castle, 1x Witch's Cottage - played with 24 for a while and got stuck on lands, you have so many various manasinks and card draw and awkward casting costs for lategame, and 25 feels right. trying out a third Castle cuz I haven't seen it with 2 (but also haven't needed it that often, to be fair) and thus am running just one Witch's Cottage. which has been fine, but I wouldn't run two with the third Castle due to awkward-mana-sequencing paranoia. Mobilized District/Blast Zone are tempting but again, don't wanna risk not being able to cast Ayara (or Underworld Dreams out the side)
still feeling out the list but this seems like a solid start for anyone wanting to try the deck
