If anyone has any ideas of what to add to this deck, I'd like to hear about them....

{"ops":[{"insert":"So my question is, do you want it to be Play Big stuff? Or more focused synergy?\n"}]}

{"ops":[{"insert":"I think the deck should focus on attacking, as soon as possible, and dealing as much damage with as much little mana as much as possible, since in Red and Black, there isn't much in the way of ramp, just straight up aggro.\n\nSo I would suggest stuff like "},{"insert":{"card-link":"Hellrider"}},{"insert":" (He has haste, and as attackers are being declared, your opponent is already being dealt damage regardless of how you attack) or on the more expensive side "},{"insert":{"card-link":"Calculating Lich"}},{"insert":" \n\nAnd to add more insult to injury since creatures are going to be dying regardless, I'd add in "},{"insert":{"card-link":"Blood Artist"}},{"insert":" and "},{"insert":{"card-link":"Zulaport Cutthroat"}},{"insert":" as a means to keep the death train going.
