A pretty straightforward aggro list built around the Trackers, a pair of cards I happen to really like quite a lot.
Tireless Tracker and Briarbridge Tracker are the meat and potatoes of this one. They generate a lot of card advantage through their clue tokens, and both Trackers will grow from having and using them. Hopeful Initiate, Thalia's Lieutenant, and Adeline, Resplendent Cathar are all growing threats that only get more deadly as the game goes on, and Initiate's secondary ability is often very useful (and easy to enable with how many counters you're generating). Support is tackled by Luminarch Aspirant and Brutal Cathar
, providing additional growth and some spot removal, respectively (continuous spot removal if you exploit day/night by holding up clue mana on your turn).
Rounding out the deck, we have a few spells: Thoughtseize needs no introduction, Fatal Push and Assassin's Trophy are good all-rounder pieces of spot removal, and Collected Company generates huge board advantage, resets after a wipe, or ambushes a bold opponent.
Finally we have my girl, The Wandering Emperor, filling out the last 2 slots in the mainboard. Excellent removal, builds a board, grows threats, she does it all (and for the low, low cost of only 2WW, what a steal).
The sideboard isn't too complicated: a little more removal for specific problems, some boardwipes, some graveyard hate, some taxes, you know the drill.
I think this list is probably gonna need some fine-tuning as I test it out, so suggestions would be really appreciated!
