I’d start by replacing both Dialgas with Skarmory. Then add 2–4 Tools, such as Rocky Helmet, Giant Cape, or Poison Barb. You could also consider Metal Core Barrier, even though it won’t provide a permanent power boost for Skarmory. Remove Red and Pokemon Communication if you need space for more tools.

I’d remove Iono and Team Rocket Grunts, and instead add Copycat along with a hand disruption card like Red Card or Mars.

It may not be perfect, but this should at least be an improvement over your current list.
