I like these ideas so how about we consolidate them?
Eviolite
Pokemon Tool
(tool rule)
When you attach this card to one of your Pokemon, show an evolution card from your hand or deck that evolves from the Pokemon this card is attached to to your opponent. If you can't, discard Eviolite. Reduce all damage done by attacks to the Pokemon Eviolite is attached to by 10 (before weakness and resistance).
Yeah, I like these ideas too. Everyone seems to make custom Pokémon ones. What about T/S/S? I've made a Focus Sash and Life Orb, but they're from past gens. I'ma check the new items. See if I can think of anything.
Edit: lol, that was fast. How about Ring Target?
In game effect:
If a move failed because of the opposing Pokémon's Type, this Ring Target will make the move hit.
This could be the card:
---------------------------------------------------------------------
TRAINER /
Pokémon Tool
Ring Target
Attach Ring Target to 1 of your Pokémon that doesn't
already have a Pokémon Tool attached to it. If that
Pokémon is Knocked Out, discard this card.
When the Pokémon Ring Target is attached to
attacks your opponent's Active Pokémon, don't apply Resistance for that damage.
---------------------------------------------------------------------
And...
---------------------------------------------------------------------
TRAINER /
Pokémon Tool
Red Card
Attach Red Card to 1 of your Pokémon that doesn't
already have a Pokémon Tool attached to it. If that
Pokémon is Knocked Out, discard this card.
When the Pokémon this card is attached to
is damaged by an opponent's attack
(even if the
Pokémon this card is attached to is Knocked Out), flip a coin.
If heads, your opponent switches their Active Pokémon
with 1 of their benched Pokémon, if any.
