I was the [Demonology]/Fire/Balance player in this game. I’ve been trying to solve it, but I’m not quite there yet. Vortoss Emblem is an option I didn’t consider, but I’m personally wary of solutions involving it rather than just killing this turn, as Ember Sparks + Dark Pact beats all of them.
With Faerie Dragon dead, the Lobber is no longer under the effect of the Feather Rune, so it wouldn’t die to Nullcraft.
Without Moment’s Peace, opponent replays Lobber, plays Faerie Dragon putting rune on Lobber, plays Mimic, Mimic->NC, Lobber->base. If you play Moment’s Peace over NC and break tech 1 instead (to prevent Lobbers from coming back and pinging base, you’re still dead to Ember Sparks + Dark pact or 2x Dark Pact.
Sergeant can’t put runes on Heroes. Second chances is interesting, though.
Here’s what I came up with so far:
Tech Drill Sergeant
Prynn to 3 runes
Play Ebbflow Archon ($6), draw.
Midori+Cadet kill Basilisk
Prynn + other Cadet hit base for 6 (12:heart:), Prynn to 4 runes
Remove 5 runes from Ebbflow to bounce and replay Cadet 5 times and draw 5 cards (rest of deck) (%2)
Play Nullcraft ($4), reshuffle and draw Cadet or DS.
I’ll assume you draw Cadet first, in the worst case scenario.
Bounce FD ($3) (%1)
Nullcraft hits for 1 (11:heart:)
Play Cadet, draw DS.
Play DS ($0), nothing left to draw
Prynn Trashes Archon and Nullcraft, then they come back
Remove 7 runes from Archon to bounce and replay OC 7 times and put 7 runes on Drill Sergeant.
Drill Sergeant moves 7 runes to Nullcraft, which attacks for 8 (3:heart:)
An adapted version of @Caphriel’s line can get the opponent to 1 or 2:
Tech Drill Sergeant + Second Chances
Prynn to 3 runes
Play Ebbflow Archon ($6), draw.
Remove 5 runes from Ebbflow to bounce and replay Cadet 1 5 times and draw 5 cards (rest of deck) (%2)
Remove a rune to bounce and replay Cadet 1, reshuffle and draw. (%1)
If you drew Sergeant first:
Play it now to draw Second Chances ($3)
Bounce Cadet 1; Archon dies and comes back with 7 runes
Replay cadet from your hand, 1 rune on DS
Bounce and replay Cadet 1 6 times for 7 total runes on Drill Sergeant
Prynn trashes Archon
Prynn + Midori kill Basilisk, Prynn dies, Archon returns
Bounce and replay Cadet 1 7 more times for 7 more runes on DS (14 total)
Move 14 runes from DS onto Cadet 2
Cadet 2 hits for 17 (1 short)
If you draw Second Chances first, you lose out on 1 rune.
EDIT: Oh duh, Caphriel has it below. I was overthinking this one a bit, I think.
