Windsweeper and Slipstream are cool, but they don't have any native bold or tough. The icons on the cards must still be important--but for these two, what's more important is what's printed on the cards. So, Firedrive stands in for easy card-draw, and as a solid automated weapon.

Also, you probably already knew this, but yeah: One Shall Stand, One Shall Fall is tailor-made for this team. Hit Windsweeper with those 3 damage counters, and throw those right back at your opponent. Add that to, y'know, the 3 direct damage the card does to your opponent's character in the first place--and there's 6 points of damage out of one action.
