Emergency Exit
Slow Start
Defeatist
Emergency Exit is the one interesting me the most since it seems to me like an interesting direction that could open a variety of niches (both offensive and supportive) based on keeping momentum. Slow Start is also quite interesting to me since I'd really like to explore the positives a slow mon could have to keep it alive for 5 turns and then wreak havoc.
Lastly, I'm also charmed by the possibilities Defeatist could open. The mention of 2 different roles on a same set sounds amazing to me.
