FJ Daisho Grenadins

This deck gets most of it's power from people not seeing harsh rules coming, but this deck has many effective ways to finish a game. Overloading a board and killing people with sweeper + disassembler triggers is one way. Ramping out very early gearcrushers and daishos, which you can tutor for with rise to the challenge is another. Lots of games you just beat them down with 1/1's and/or the many small pings to the face also add up a lot. Vanquish could probably find a place here if there are too many harbingers in the meta.
