I like the farsight alternation
Saw a lone Trist with regular wards around baron while her team is defending against 3 down inhibs at base. Figured she'd BD so I placed a trinket at red. Found said Trist on blue ward so I told my team she will BD. She placed a ward in our base and her Gnar duo TP-ed into it. Irelia and I B-ed, killed them both and my team won 5 v 3.

Always make sure at least one person is using blue trinket/upgraded red trinket actively!
