Hmm...
^ If you don't want Fighting support OR Malamar, maybe Greninja-GX and some kind of snipe-and-move-counters deck complete w/ the possibility of Tapu Lele psychic non-GX(the promo one), although finding that pokemon now w/o worry of having to wait until TPCi is ready to pull it out of the closet and allow sales of its associated product: its pin collection box. TPCi was expected by the web to pull such box from the closet yesterday, but for some reason, the product is STILL listed as delayed on web. Either they're lazy, forgot to update their product gallery while the post office failed to deliver it to stores(and maybe it's delivery to stores is due tonight for a Monday release at Wal-Mart or even another specific retailer, while other chains are barred from releasing it until FOL's street date, when its sales could be overshadowed by FOL product sales, meaning the pins will not sell as much), or another delay will pop up on Monday to who-knows-when, or if Gen 8 is coming this year, maybe it's possible the box is going out the localization window by cancellation of the outside-Japan product, crippling the snipe-and-move-counters idea in the process...
^ Or, if you dislike Greninja's Golisopod(First Impression for 120 before Weakness application) weakness, how about the new Alolan Marowak, in case you have an absence of Energy from hand and discard: a situation that means you can't power up Dusk Mane, as all the energy's in your deck rather than your hand, which Alolan Marowak's Limbo Limbo can address? Plus, Steel Frying Pan can help Dusk Mane(Ultra Prism)--or even alt-type Steel-type Dialga-GX(Forbidden Light) in terms of ensuring the attachee's survival vs. Fire type decks w/o Field Blowers to hasten their discard...
^ That's all the other selling points of this set, unless you count the new lightning Magnetic Circuit Magnezone that ensures that the main energizer of the Raichu-GX metadeck won't go away after rotation, as without a Lightning energy Deluge, Raichu GX, while not due to rotate this fall, Raichu-GX will miss the absence of the possibility of infinite Lightning energy attachments... Still not sold? There's always next set, but what if the MalaMew metadeck that comes from this set owns you in the meantime to make you regret your possible decision not to buy Forbidden Light packs?
