No part of Moses CoW is cbn. It negates stuff.
Anything that grants CB-anything is CBN
The way I like to think about this is that when the card says it cannot be interrupted (or same for CBP or CBN), then there is NOTHING you can do to allow it to be interrupted (or prevented for CBP or negated for CBN). Therefore you cannot negate or prevent or interrupt those modifiers..there is no way you can do that.
Note: Like Moses, cards that negate other cards are different types of abilities. As pointed out, he is not CBN
Note: There is a way to get around CBI, CBP, and CBN abilities if you have a way to “instead” whatever they are trying to do. While it gets around their ability, it is not trying to negate it.
