This is a good early pool 3 discard deck I used to get to rank 70 in the first few seasons.
The ideal curve would be to snap and skip 1 even if u have blade becuase it tends to discard the wrong one. 2 either skip play morbius or discard swarm with colleen. 3 play lady sif. 4 play jubilee or other remaining. 5 play hell cow if u dont have hela in hand or other low costs. and finally in t6 play hela and win.
