well Trump card is just overpowered we all know it his ability grant him that. both BM and Kaido has top advCoC and couldn't defend themselves against it. Kid is still a novice in using CoC , and he use it probably without realizing it.
the only ones who can use it properly this arc are Kaido , BM and Luffy , even it doesn't mean that every advCoC user has it as a offensive trump card. BM used it only against Page One or now for defense which means her homies attack are more powered.
so yes Kid's CoC haki is not good enough yet.
Zoro can use it to a good degree thanks to Enma and with a huge drawback of having his stamina absorbed.
