It seems like every deck is going to be inconsistent next rotation but I can think of many different engines to go in many different decks. If you think of any more, post them below! My list: Electromagnetic Radar/Dedenne GX/Pokemon Communication (for fast, aggressive decks like Malamar) Pokegear 3.0/Professor Elm's Lecture/Pokemon Communication (for decks with 60 hp basics) Pokegear 3.0/Jasmine/Jirachi/Pokemon Communication (for metal decks, as well as basically anything else) also maybe a metal tech like Jirachi prism star Pokegear 3.0/Pokemon Maniac/anything with 4 retreat/Pokemon Communication Cherish Ball/Order Pad/Jirachi (for tag teams) Green's Exploration/Cherish Ball/Mismagius (Unbroken Bonds)/Dusk Stone/Mysterious Treasure (for tag teams) (Fairy) Alolan Ninetales GX/baby Whimsicott (Unified Minds)/Shiinotic (Ultra Prism) Judge's Whistle/Acro Bike/ Pokegear 3.0 (Any deck can play this) also, combined with welder, is a good fire engine Jirachi/Order Pad/Mysterious Treasure (for dragon and psychic) Dunsparce (?) Disclaimers: Yes, I know treasure, net ball, and radar exist but those aren't "engines" Order pad, judge's whistle, acro bike, p. comm, red's, cherish ball, and pokegear can be played in any deck but are not an engine by themselves, only in addition to other cards. Salazzle helps fire out but you still need an engine to get IT out Note: I am constantly editing this with suggestions from below. If I don't have something on this list that you commented (AKA I forgot), feel free to say so. Just give me a day or 2 to add it. If you are wondering what I mean or what the combo is, ask! I will gladly specify.
