Midnight Gale Tempo V2

Final version. Added the Sprite/Felrauk package from those cool Feln tournament lists. This is now a very efficient and effective gauntlet grinder. Let's go through some general play patterns:

Twilight Raptor: Always play the bird turn 1 if you can, even if you have Mom also. This is a more aggressive list than the standard Feln midrange that's been running around, and the extra two turns of damage is better than the extra token. If you start with tapped mana, bird, and mom, then you can hold the bird, play mom t2 and bird t3, or both t3. This is a marginally worse line of play, and part of the reason why Crests are comfortable in this deck.

Blightmoth: Moth is a control card here. It will win practically on its own against dangerous tribal aggro decks in gauntlet, particularly grenadins and onis. Treat it like a kill spell, and don't play it against an empty or fat board unless you have no other means of activating Throne Room.

The Throne Room: Know your matchups. Turn 3 is your most important turn, and which cards you play will depend on who your opponent is and what else you have in hand. Throne Room is the better t3 play when you anticipate a big threat that Daraka can tap down or block (ex. Worldbearer, Impending Doom, Amilli, Makto, etc.). Face aegis is meh in gauntlet, but helps against burn occasionally.

Midnight Gale: Always play Gale on curve if you can. Do NOT wait to play Mom first if you can play Gale first. By virtue of stats and color, Gale dodges a huge number of tempo-positive removal in gauntlet (annihilate, torch, suffocate, etc.) and most opponents will be forced to use a whole turn to Slay, Vanquish, or Feeding Time, which is fine as your birds and moms continue to swing in.

Condemn: If your opponent hasn't played a 1-toughness creature by turn 3, just cast it to face at end of their turn and get Avoid Death. Priority Condemn targets are the usual suspects: Ronin, Initiate, Pyroknight, etc. You will normally fetch Avoid Death against a non-threatening board and Edict if there's a Sandstorm Titan or something that needs killing. I will often fetch Edict against a topdecking time deck just in case that surprise Sandstorm comes out. Dark Return is best used on Reaper or Champ-kun, but can be used on Lookout or Gale when in need of card advantage or a blocker, respectively.

Umbren Reaper: Note that he and Black-Sky both count towards Throne Room without having to swing. AI will ram head first into Reaper, so use that to your advantage. They'll Annihilate it when at 4 life, for example. Dark Returning it means 10 face damage easy.

Lightning Sprite: Highsky Lookout helps generate shit cards to ditch with it. You can comfortably sit at 4 mana and ditch the rest unless you have Champ-kun in hand or it's an aggressive matchup that needs a little Black-Sky. Always activate Sprite with your matchup-dependent top end in mind. If you can race, dig for birds and Gales and removal, ditch mana. If you need to bust through something, dig for mana and Champ-kun and ditch small threats. If you're getting bashed by grenadins, dig for mana and Black-Sky and ditch removal, etc.

Permafrost aggressively. Permafrost any early unit that either blocks you or forces you to block, like Owlet or Ripknife respectively. Damage is paramount. Stacking damage early game means Reaper or a 4/1 sprite can suddenly finish them off later after stabilizing.

Highsky Lookout: Save him for when you can invoke, unless you have Throne Room out or really need a block. He can also bait some removal against Kiss of Death or something that plays a ton of it, then you can invoke him again later for value.
