This is my first handmade deck since the beta wipe. I don't have many cards. Only wildcards used were 2 rare ones for the two punisher spells, but I haven't drawn Risk Factor yet so I can't tell you if that's any good.

7 x Swamp
9 x Mountain
4 x Cinder Barrens
1 x Dragonskull Summit

2 x Diregraf Ghoul
3 x Grasping Scoundrel
3 x Ghitu Lavarunner
1 x Goblin Banneret
1 x Dire Fleet Poisoner
1 x Kitesail Freebooter
1 x Runaway Steam-Kin
3 x Viashino Pyromancer
1 x Captain Lannery Storm
1 x Captivating Crew
1 x Siege-Gang Commander

3 x Fungal Infection
4 x Shock
4 x Lightning Strike
1 x Sovereign's Bite
1 x Swashbuckling
1 x Direct Current
1 x Repeating Barrage
2 x Risk Factor
2 x Sword-Point Diplomacy
2 x Trumpet Blast

I mean, it's workable. It's got a lot of mediocre cards, but you're working with what you have.

Prophet doesn't really seem to fit because you don't have an easy route to Ascend or big CMC cards to pay off, but I don't know what other options you have.

I saw other people playing prophet and thought it was cool. Cracked another Risk Factor and a Runaway Steam-Kin so I added them to the deck and took out prophet and a swamp. But 21 lands might be too few

21 should be fine.

Put the swamp back in and took out a mountain. Updated OP with current list. Won my first two ranked games with this deck. Not sure if this wants Light the Stage when it comes out. Haven't managed to crack anything to add the this yet
