Well if you only play with DCE, you could always turn your deck into a mill deck. Make them discard cards, knock off their energies, disrupt their hand, reduce their hand size.
Team rocket's handiwork, team flare grunt, crushing hammer, enhanced hammer, judge, N, parallel city, guzma, pulmeria, those are some of the cards that come to mind.
As for pokemon you might want to include garbodor (has ability garbotoxin) that way all abilities on the board are cancelled out, shining hoopa (shining legends set), xurkitree gx and bunnelby (primal clash).
