Used Kasendrith's Musical Dredgewalker list
https://eternalwarcry.com/decks/d/2I5RuhnNXOQ/musical-dredgewalker as a base. Removed some spells for some units. Toxicology is probably the card you'll miss most, but we still retain 8+1 ways to discard a card from hand and there's really only 1 card in particular you
want to discard and that is
Clocktower Sentinel.
Step 1) Fill your void with units. Many of those units come back over and over.
Dawnwalker,
Endless Nightmare, and
Ephemeral Wisp will all rack up a lot of frequent flyer miles traveling from board to void and back again.
Step 2) Mash opponent's face with your extra large void-juiced payoffs in super surprise fashion.
Valles Rex and namesake
Bone Music can be both be played end of opponent's turn for a TON of out of nowhere damage. Nothing like putting 30+ damage on the table after your opponent powers down for a board wipe.
Step 3) ?????
Step 4) Masters.
Deck has been running very hot. Still a smallish sample size. 38 games played, 33-5 from D3, with an 18-5 record since reaching Masters.
