Cards suggestions/fanmade

Yo, that Lance card idea is really good. Super on point. I love how it would almost only ever be useful in a Dragonite deck.

How about some trainer cards that act as meta-stabilizers. Generally you'll find there are cards that can be really potent against a certain deck or archetype, but the downside to running it is it's a dead draw against other decks. For example:

Psy-Inhibitor (or my preferred title Spoon Straightener)

Trainer Card

"Remove one psychic energy from your opponent's active psychic pokemon."

Cards like this are obviously printed to deal with overwhelming decks in a meta cough Mewtwo Ex cough, but they do pose interesting decisions particularly in competitive or tournament formats where as a deck builder you have to decide if the power boost against one potential deck in the meta is worth making your deck worse against all others.

Here's an interesting idea:

Baton Pass - Trainer Card

Swap your active pokemon with one of your benched pokemon. All energy on the active pokemon is transferred to the new active pokemon.

So this card could accomplish a couple of things. First, it allows bulky frontliners with high retreat cost to actually be played without being an automatic point loss. You can pump them with energy and threaten damage while also being able to safely pull them back without paying retreat or losing the energy. Second, it makes for a cool way to move energy around that is strong, but has limitations. For example, it's great for stacking up energy without giving up the ability to attack, and then swinging into a benched hard hitter. Obviously better than X-Speed in that context. However, it's lousy if you want to swap into a pokemon that you know is going to get ko'd next turn. You can't use it to throw in a fodder mon or a revenge killer without losing all that energy you'd like to keep on the current active mon. So in those situations it's worse than x-speed or just retreating. It also threatens a new kind of swap that opponents need to consider and plan against.
