Absol EX combo

Absol has it kind of rough with its offensive and stall options. But if you do build such a deck, you could make it a secondary attacker for late-game if things don't go well in a Darkness deck, since once your opponent only has 3 prizes left, you can reduce your opponent's hand to 3 or fewer cards with Iono and Roxanne, which would then combo well with Absol's main attack. The only problem would be if your opponent is all set up and stuff, so you could run disruption cards that discard Energy, Stadiums, Tools, and some cards you may find helpful for that would be Lost Vacuum, Crushing Hammer, and Devolution TM might come in handy too to ensure knockouts.
