Rakdos would be proud. Rakdos was definitely my guild last time (along w/ good 'ol Dimir), and this rotation I want to try it out. So far, I have this record on the playtester (Wins/Losses/Ties):
U/W Delver: 4/3/0
Bant Midrange: 6/0/0
U/R Delver: 5/0/0
It's currently able to take out Zombies, and is neck-and-neck w/ Delver. Thoughts, comments, and +1's are appreciated, and will be followed by handing out candied hands (Reference to Carnival Hellsteed).
Having a record on the playtester doesn't mean much. You know how to play your deck and probably don't know how to play everyone else's.
Get that record in a tournament and I'll be impressed.
I never said it didn't need edits, either. Though, to some extent, you have point. I know Delver like the back of my hand (I played it in FNM's once upon a time) and Midrange is no stranger, either. Zombies, on the other hand, I'm still getting used to.
Btw, Challenge Accepted.
It looks good, though having only 22 land with 2 bonfires and 2 rakdos return seems too low. I'd go up to 24.
