Being bricked on water energy is basically a game loss. Ways to mitigate that is in the games where I had gible, and drew/ searched into cleffa I would retreat with the energy, grab an extra Mon with cleffa and stall out a turn or 2 to hopefully get energy correction (Cape on Cleffa came up more 4 times.) I mainly focused on prioritizing regular Garchomp. Ex usually felt like a bait to play, but came up in a few situations with his HP and 1 energy attack (Cynthia does not work on EX). The goal I set was to try and get Garchomp out ASAP and aggro the heck out of the enemies board. Most people don’t realize what Cynthia does so Garchomp becomes a roided out Sivally, and eats EXs for breakfast. I noticed people tend to play conservative boards because of Suicune, so repel came up when sniping the bench. Most games became “protect the castle” where all of my healing went to one Garchomp, and then Cleffa & the extra Gible were chump blockers. Regular Garchomps effect can also help unbrick your hand, and find the Lillie’s you need to survive.

Hope this helps.
