Ghostmon> Silk Tree is a good choice if you want a Crit+react team. She will have a good place in your 1st team.

Tarragon is very good but I guess she is better for Crit+Counter with girls like Kayana, Anemone and RG China Roots.

Tall Stewertia Christmas is good too but I prefer Balsam for everything.

You should also think to Japanese Anemone Relaxed Queen (or THE Queen). As a wise man said one day, "some things can't be solved in one turn". That's why the Queen is made for.
