2: Create two 1/1 black Nightmare creature tokens with "At the beginning of combat on your turn, if a card was put into exile this turn, put a +1/+1 counter on this creature." 7: Target player exiles the top X cards of their library, where X is the total mana value of cards you own in exile
And adding in some cheeky wincons like Reckless Fireweaver, Nadier's Nightblade, and Revel in Riches can really push games in your favor
The loop is a four-card combo involving Yedora, Grave Gardener, Temur Charger, Den Protector, Ashnods Altar, and an effect like Chromatic Lantern or Dryad of the Ilysian Grove
Note that nothing needs to line up, any spell is exiled, and any spell revealed of the right cost is cast
These are spells with no determined casting cost, meaning you can assign whatever number you want to it, provided you have the mana to spare
Your opponents can't cast spells during your turn
