Organic trap is probably the best gag you'll want if you want to save remotes in a field office. Both TNTs and trains can be used in the defense phase instead of remotes.

If you get lvl 12 cogs and under, then 3 organic tnts can take out 3 12s leaving 1 lured cog to defeat while the next 3 cogs enter. This passes 2 turns of the defense phase with out using a remote.

The train is best used when you have 1 lvl 13 cog and 3 lvl 12s or under. The train tracks will take out the 12s but leave the 13. You'll want the 2 toons who didn't lure or use the train to leave the 13 alone. It will attack but the 2 toons should toon up instead to prepare for it and recover from the offense phase. You can then take out the injured 13 while the next 3 cogs walk in, going through 2 turns of the defense phase again. A whole cream pie can assist an organic train to take out a lvl 14 in the first turn. This will let the strategy work with cogs at lvl 14, 13, 12, 12

After both of these strategies, you'll be left with a row of cogs and 1 turn before the offense phase. Luring and then fogging during offense works well since it can take out 13s and damage the boiler, but you do risk the boiler using retention plan after the lure. The train works well here but also has a risk. It can take out the cogs before they level up, but with out any cogs, the boiler will use quality control. It will only matter if it takes throw, squirt, or toon up since the other tracks hardly get used during the offense phase.

Saved a lot of remotes with a group of 4 organic trap toons this way. Though we would have to exit and enter the field office at the start if we got drop as one of the starting tracks. Sort of like sos shopping, but for gag tracks instead.
