This market seems off to me. Do we really need to have access to 4 backlash? Would we be better off with a Rindra's Choice, Feeding Time, or Black Sky Harbinger? Also, how did you wind up on the Draconus in the market? Is it for a specific matchup?
The Backlashes were for Answer the Call, but they pulled their weight in a lot of match ups. Rimescale is good against Time midrange and is the main answer to Dawnwalkers. There are options for when you're ahead (Backlash), board stalled (Crystallize), and behind (Rimescale/Perma). Rinda's Choice and Harbinger are also fine choices, but I wouldn't play Feeding Time because it doesn't generate card advantage or tempo and I want higher potential from my market cards.
