Ramp Suite:
Fire Diamond
Sol Ring
Burnished Hart
Caged Sun
Basalt Monolith
Gauntlet of Power
Solemn Simulcram
Palladium Myr
Iron Myr
Worn Powerstone
Pretty simple easy stuff, its just that you want mana to combo off or do things. I could, and maybe should be playing more mana rocks, but I find that hitting one land drop every turn is really good.
Draw Package
Staff of Nin
Reforge the Soul
Wheel of Fortune
Faithless Looting
Ignorant Bliss
Wheel of Fate
A little weak on the draw, I usually impose the rule on myself to always cast a wheel if I draw it. A fun play is copying the wheel to mill yourself and (hopefully) hit a past in flames and try to go off. Hostility is really really good card and it does shuffle back in so don't worry about the discard. Ignorant bliss is fun to save your hand from discard or the wheels.
Storm Crap
Increasing Vengeance
Mana Geyser
Fork
Past in Flames
Pyretic Ritual
Reiterate
Seething Song
Charmbreaker Devils
Mana Geyser
Surreal Memoir
Dualcaster Mage
Howl of the Horde
This is half of the combo, or you just use this to drop your Dong on turn 2 (pyretic -> Seething Song- > Spray 'em in the face with your dong), or just play just inferno titan -> heat shimmer/kiki shenanigans.Rituals are also just some of my favorite cards so I tried to fit as many in as I could. I also just think forking someone else's Kodama's Reach is real fun.
Blinking Stuff
Heat Shimmer
Conjurer's Closet
Blood Clock
Beetleback Chief
Inferno Titan
Twinflame
Oni of Wild Places
I just threw in most of these just recently, trying to make Dong a little bit stronger. Also have some real good ETBs like Inferno Titan or Simulacrum. Blood clock is really quite bad for your considering you are recasting Dong, just remember that if you play it you can bounce the blood clock once your enemies use it to combo out.
Utility
Brittle Effigy
Spine of Ish Sah
Viashino Heretic
Smash
Blasphemous Act
Goblin Welder
Duplicant
Chain Reaction
These cards in my opinion are almost just staples in any mono-red. I always play these in my decks.
Burn
Pulse of the Forge
Earthquake
Fireball
Hostility
Guttersnipe
Flame Slash
Furnace of Rath
Incinerate
Char
Devil's play
Banefire
Sulfiric Vortex
Zo-Zu the Punisher
Sulfuric Vortex
Satyr Firedancer
Some of these cards are bad, some of them are good. Burn cards are surprisingly good at removing various threats that come down onto the board. Pulse of the forge + Hostility is a really good way to win.
Random
Zealous Conscripts
Goblin Sharpshooter
Runechanter's Pike
Lightning Greaves
Tenza, Godo's Maul
These cards are here to bash face. Runechanter's Pike commonly bashes for 5+ which is always nice. Tenza just makes Dong Zhou a much better creature. Conscripts is pretty good stuff, Goblin Sharpshooter is one of my favorite creatures.
In this deck losing is common and I like doing dumb things. Wheels always bring in the groans from everyone, but usual end up accelerating the game state. It always feels bad to slam down Furnace of Rath only to have the person you pass to kill the whole table. I really enjoy the stupid wins.
Current Dong kills: 4
A good playstyle with dong is to make sure you are constantly making dick jokes. Really changes the mood at a more serious table when you show up with the Dick Tyrant to slam some kids.
