What's better for a burn-tremor team, thumb Rodya + Heathcliff or Rodya and Ryoshu (that killed Heathcliff)

I have a burn tremor team with thumb trio, dawn trio and mb Outis, who I am thinking of replacing with Ryoshu.

I'm wondering if it's worth having Heathcliff in that team, or if it would be better to have Ryoshu eat him and use MB or Liu Yi Sang instead.

Would his free attacks after Rodya + occasional s3-2 end up doing more damage, or would it be Ryoshu + another unit.
