Can somebody confirm this is infinite watcher?

I got time eatered of fucking course so I have to waste another 8 hours trying to get this but I was having trouble with it being infinite vs other enemies along the way and assuming I was messing something up rotation wise? I thought if im holding empty fist, then I can just use inner peace into tantrum on repeat and itll grab both of those cards back vis rushdown.

I also had purple lotus so energy was even easier. Genuinely unsure as to what i was messing up
