I think these kinda decks are too flexible and can be too broad of a range to really pin it down as a 'type' that needs a term. Most decks that are combining elements from two or more deck types don't need a name to denote that.
I always just say "Its a Glacier deck that can play fast"
because that is different than "Its a fast deck that can build strong servers"
The statements show the stronger focus.
We don't need to shorthand everything imo.
'A faster Glacier deck' or 'A more stable/solid Rush deck' do the job just fine.
just me tho
