Giada, Font of Hope is an Angel tribal deck that wants to curve out flying creatures and grow them with +1/+1 counters.

The main plan is:

• play Giada early,
• cast Angels ahead of curve,
• build a flying board,
• then win through combat damage.

Key synergies:

• Giada + cheap Angels
  Cards like Inspiring Overseer, Segovian Angel, and Stalwart Valkyrie enter with extra counters from Giada and help snowball your board.
• Token makers + Giada
  Emeria Angel, Decree of Justice, and Castle Ardenvale make more creatures, which increases how many counters future Angels get.
• Lifegain package
  Ajani’s Mantra, Dawning Angel, Seraph of Dawn, and Holy Cow help stabilize your life total while supporting cards like Griffin Aerie.
• Protection effects
  Unbreakable Formation, Make a Stand, and Your Temple Is Under Attack protect your board from wipes and bad combat.
• Big combat finishers
  Sanctified Charge, Thraben Watcher, and Herald of the Host help turn a wide flying board into lethal damage quickly.

The deck wins by overwhelming opponents with large evasive creatures while staying resilient through protection and recursion like Karmic Guide and Defy Death.
