Going infinite

DECK EDIT: Do note that both Waystone Titan and Syl, Hand of the Cabal are good option and interchangeable, but Syl, Hand of the Cabal allow for better aggression, better Calderan Gunsmith synergy when you have a big board as well as more consistency (due to the reduced chance of her being a dead card) while on the other hand Waystone Titan allow for a better Calderan Gunsmith on smaller board, work as a better blocker and can potentially refill your mana when played. Using both is also not too bad, but i believe that Black-Sky Harbinger is a better fit due to the added sustain it give you, being a flying blocker is also nice and the sustain it gives you. Also added End of Hostilities since it work better with Syl, Hand of the Cabal or Waystone Titan, West-Wind Herald and Calderan Gunsmith. It also can pivot into a good defensive option.And finally Combust to replace Burn Out for many reason (because the deck need hard removal), tho I do wanna say however that i learned how good Burn Out is with this deck and it is still an interesting option. Nobody expect the Burn Out inquisition.

Deck that can go infinite if you set it up right.

And how do you set it up right, well its simple (not really).
First what we need is a board with 2 West-Wind Herald , 1 Cabal Spymaster , maybe 1 Waystone Titan . Then what you need in the void is 1 Calderan Gunsmith and the fun part is here since you get multiples paths depending on what you have in your void and on board, but you need at a way to create or draw the Calderan Gunsmith for this your option are Grasping at Shadows , Dark Return (which require the Waystone Titan ) or Mirror Image (which require space) . The second thing you need in the void is a way to sacrifice a unit. Your option are Burn Out or Devour (which combo well with Waystone Titan at the risk of decking yourself or discarding the Calderan Gunsmith when used with Dark Return ).
Once this is set up all you need is to play one Calderan Gunsmith (while keeping 1 in the void) and the rest is a test of your skill and apm.

But you might say that this is a lot of combo piece to draw and even more to play. And to that I answer, you are playing an infinite combo, did you really think it would be easy to set?

But to help you draw all those card we have plenty of help, first is Xo of the Endless Hoard (need no introduction), Crunch, the Hoarder (because hoarding is cool, so is drawing) bonus its an infiltrate which work well Cabal Spymaster . Wisdom of the Elders (also need no introduction).

Essentially your game plan is to draw and slowly set up the combo, protecting your combo piece so they don't get silenced or polymorphed, once youre done setting up with the Calderan Gunsmith in hand or a Mirror Image while having a Calderan Gunsmith you're good to go

Most of the game you're gonna win will usually not require you to play the combo and might often end up with you outsmarting the opponent, getting the luck of Satan (both Hercules and the Devil) or Calderan Gunsmith just doing what it does, being good.

Do note that face aegis will shit on this combo except if you have a way to repeat it without fking up the sequence
