Modern spirits: a fast, heavily ramped variant.
Thanks to Arbor Elf and Utopia Sprawl, turn 2 Collected Company as a response to the opponent's play can occasionally happen, giving a warm fuzzy feeling inside. Generally however, you should be able to drop a turn 2 Geist of Saint Traft, Spell Queller or a 2-drop with mana up for a Path to Exile.
The deck does what you would expect it to do, however 'automatic 4-ofs' have been scrapped as a philosophy here (after running spirits extensively in standard and contrasting with the modern experience). I am finding that Mausoleum Wanderer and Path to Exile in the same deck just don't work, and the Wanderer is too easily played around and doesn't necessarily do enough as a card slot against a lot of decks, when we have 12 1-drops here. He is however on the sideboard as our effective Spell Pierce against creature-light/creatureless combo decks like Ad Nauseum, where we can board out the Path to Exile and board in our lorded and buffed counter-on-a-stick.
Similarly, Selfless Spirit is relevant against some decks and not against others (2 copies here with one on the side), and Rattlechains sees 3 copies as even when the hexproof doesn't see use, giving flash to captains and geists is relevant.
One interesting design choice I have come round to is Duskwatch Recruiter
for 2 (maybe even 3) copies. He can do a number of things, allowing you to cheat in your 3-drops more cheaply when you are not overwhelmed with mana, or fixing a mid-game mana-flood crisis, giving you a card filter and mana sink through which to draw into relevant stuff. I was running 2x Wall of Omens to stall aggro decks while drawing, and that may still be the better choice, I am not sure. Generally however, I am curious to try this dude, who may speed up a slow hand, or replace a hand which plays out by turn 3. Just like the 1-drops, having all 2-drops which help the 3-drops to 'happen' is the key here as the Drogskol Captain and Geist of Saint Traft are the powerhouses here, with the Spell Queller doing his thing, and the neat Phantasmal Image copying a captain, or even a Queller off CoCo.
The Eternal Witness is proving itself to be an amazing 2-of, normally either fetching back a Path to Exile or a Collected Company.
Onto the sideboard: The Wall of Omens is brilliant against aggro, and is only pushed out of main deck for the moment as a trial run. Ideally I would have two copies available, but slots are competitive. The additional Selfless Spirit is there to fend off white and red board wipes. As noted, the Mausoleum Wanderer is basically my Spell Pierce when needed to stop big combo pieces, with the Mana Leak being additional multi-purpose counter. The rest, I believe, speaks for itself, hitting artifacts, graveyards, and combo plays.
