I'll go ahead & propose [[Jaya Ballard, Task Mage]]. Her abilities do not directly connect to [[Tormenting Voice]], but because they all require you to discard a card, the deck I built ends up with a lot of card draw for a Mono Red deck. Link below, might help you find similar cards you like.

As a second option, have you looked at [[Immodane, the Pyrohammer]]? Much faster deck for when you want a quicker game. Just remove the [[Blood Moon]] if you want to run in bracket 3.
