Brick or Trick?

In the classic Ceruledge ex vs Gardevoir ex matchup, you notice a critical flaw in your opponent's setup - they open with Fezandipiti ex in the active! You run your "blind toss your hand twice" routine but only discard 3 energy in the process. You pass your turn, your opponent grunts, attaches Bravery Charm to Fezandipiti, and passes their turn. Is this an opportunity to win the game on only the second turn!? If only you had a way to do 260 damage...
