Q&A paragraph mentions “Twisted Fate, Gambler”: go to paragraph
Hwei, Brooding Painter says "do the following based on the discarded card's type ..." Unlike our previous reflexive triggers printed on cards that use a similar template (cf Twisted Fate, Gambler), Hwei doesn't say "do one of the following ..." As long as the card has the appropriate type, you will put the corresponding reflexive trigger on the chain. If somehow there existed a card that was a spell unit gear, you would put three reflexive triggers on the chain when you discard it to Hwei.
