Unless I'm missing the text of "This attack isn't affected by weakness or resistance", you should be able to. There is a Wattrel with the same attack from the previous Triplet Beat. With that and Murkrow, you can hit for L and D weakness respectively, which does hit Lugia and Gardevoir quite nicely. Flamigo is just there to tutor out the correct card you need.I don’t understand the 20x damage decision. Especially with your main attacker unable to hit for weakness. I like they acceleration, but damage cap is too low.
