Assuming this still sees a 2-pack release with the same sort of accessory pack-in as Ironhide/Prowl, I'm just gonna want the blast effects. I managed to get the Ironhide/Prowl pack for well below retail here -- blast effects, an opaque-plastic Prowl I could frankencustom up with Siege and Earthrise, and a first copy of the Ironhide mold whose headsculpt can pass for angry rather than dying. Now I just need a 3d printed non-broken windshield or something.
But this... Don't need Brawn, and I'm keeping Earthrise/Odyssey Ratchet over SS86, and even if I were getting the SS86 it'd be the standalone Voyager. So it's down to the blast effects, which (like the RID2015 clear plastic armor bits) I've grown distractingly fond of.
