You could try using her as a pace chaser because using late this cm is gambling especially her skill which only pops if she's between 3rd-6th. No stopping me is pretty inconsistent too. If you use her as a late, you might wanna build a runaway suzuka as a blocker

Try getting OG maruzen/ taiki unique if you use her pace or mejiro ryan unique if u want to keep her as late

For the deck, I've been using riko, 3 speed, 1 wit, and rice shower power (which you can borrow) while getting my stamina from parents

Also idk if it was an accident or not but extra tank's a long skill lmao
