Sources on equivoque?

[Antonio Diavolo]

I feel like good equivoque can be a really powerful tool but most examples I've seen of it are really poorly done. I feel fairly comfortable forcing decisions regarding 2-3 objects using it (for example tricks where they have to pick one of two coins or piles of cards) but trying to narrow down an entire deck to one card is sort of confusing to me. I understand that you have to use semi-ambiguous language that sounds specific and can be interpreted in different ways(i.e. take either the red or black cards out). However, I've never really found language for it that I was happy with.

So yeah, what are some good resources for learning proper equivoque techniques?

Thanks everyone!
