I agree with what everyone else has said here… this is too clunky to use outside of OoO in PvP and that’s not a good idea because there are too many counters to OoO and there are much better options than this.
The SS is interesting except 400s is super long and 220TU crazily high. It’s basically for very niche use against super buffed enemies. As always, we have to add +3 cost for the pleasure of a legendary to have their secret skill but mythics are always +1 or +2 
Double bloodthirst is extremely clunky here, either needing you to run multiple Pupupa and really go all-in on this plan or finding a sleep enemy. Union focus seems pointless considering it has dual-target moves. It’s just all reading as so clunky to use.
The one very obvious setup is Mantisamurai + this + Pupupa, for use in PvE. I can see this as a decent combo for newer players but nothing more.
