This is probably a ton of fun to play

Why is the Wooded Foothills in this deck?

Diskord Its just there to reduce lands in the deck. Using it pulls 2 lands from the pool rather than 1. Making it easier to hit your creature drops and stuff. Its also useful for deck shuffling if needed and most of the time the 1hp does not matter. It can be subbed with a regular mountain or just another fetch land that searches for Mountains. I'n not running 4 more fetch lands as it would be a bit overkill. Really I would only put 2 more in at the most and even that could be pushing it.

Can you post your results with this deck?

Flooremoji I mean I haven't played this deck too much. I went 4-1 in a modern tournament the first week I played it and 1-4 another week due to bad draws and consistently being placed in vs players 1 win above me already. Is that what what you're looking for?

Why warboss over rabblemaster? That card seems less powerful for the multiple threats in 1 spot

Just when you do play the deck, it's not even necessary. :) Just curious

vomitpile Legion Warboss has a much more lasting effect on the board state while allowing for more defensive play if needed. This is mainly due to the mentor effect that is fairly useful if it comes in after Metallic Mimic allowing you to buff creatures that might have not received the Mimic's Effects. While it might not be as damaging as Goblin Rabblemaster I feel that it is much more reserved in its play and responds better to spot removal.

Honestly if you just remove two of the Murderous Redcaps and one of either the Stingscourger or Subterranean Scout you would be able to run both. That or you can just remove the Legion Warbosses and replace them with the Goblin Rabblemasters if you want a more aggressive deck. Honestly I updated the deck to its current state for testing of the replacement in the next few weeks.

I guess it would be a better idea to run both to test their effects so I'll update the deck today.
