I honestly don`t feel like han helps alot againsnt cloud team cuz it will only permanently remove samui`s buff. Ay himself scales with chakra so that cant be cleared, barrier buff when using darui cant be cleared by han and by the end of the round when main gives shields his passive buff will be on again. Just my reasoning against that particular team. About Han overall i think thats his spotlight is kinda over now, he shined when he was first introduced to counter the meta teams at the time but now meta isnt revolving much around buffs so in the long run i feeli like gnw treasure should be better. And btw if you want an easy team for arena i usually use a different one every month to get 6 path and this month i used roshi wind main kurotsushi asuma wb with dust dance the 10 hit standard, 10 hit chase, wind dance and last passive can be clones or blindness and rhino as summon.
