Cancel Leader cancels the special ability of any leaders that you have in play so the best bet is to only have one Leader in a deck. Strike Back means you always go second in the first round of a fight rather than it being randomly determined. If both people have Ashigaru its determined randomly who goes first in the first round like normal.
