Hidden Dragonslayer is a very good card in a format defined by G/R Devotion, Ensoul Artifact and red decks (against which Dragonslayer can sometimes find a target and always present a lifegain threat), Ojutais Command can do some work returning a fair few threats in the deck while providing some additional value, Mastery of the Unseen is a great sideboard card
You choose any number of target players as you put Stonespeaker Crystal's ability on the stack and exile their graveyards as it resolves
Selling in bulk means you just need to list them oncealthough it may help to highlight the standout cards in the collection
It makes me think of Night Hags from D&D, which are among some of my favorite fey/fiend creatures in the tabletop game
This means that Brightstone Ritual has no true upper limit, and it is likely to generate more mana than even Seething Song in a goblin-themed Commander deck
If an effect asks you to divide damage among targets, you must divide the unmodified damage before tripling it
