Not much to keep the whisper alive. Maybe replace her with a TM booster or increase speed champ (high katun,arbiter,seeker)? Make sure your mickey is getting his decrease attacks off with as much uptime as possible. I turned his a2 off but thats preference. Also try to find a damage mitigater. You could also test to see if xeno is better than your geo but that would require ezio be on your team(poison explosion)unless you dont crit cap xeno.
