Fling what else can it do? Clever Combos, and Pickup?

Question

I have a few question about Fling, and Pick Up ability.
What would happen if I threw
-Eject Button thrown to switch them?
-RedCard thrown to switch you?
-Colbur Berry thrown at Psychic type?
-Eviolite thrown at a pre-evolution?
-Different Pokeballs what damage?
-Metronome will it reset the multiplier?
-Leftovers but only one time?

If I had Pickup ability and used Eject Button can it re-enter to use pick up?
What if I use trick to switch items with someone with pickup can they pick it up after use?

Answer 1

• Eject Button has no effect
• Red Card has no effect
• Colbur Berry would reduce the damage from Fling
• Eviolite has no effect
• PokeBalls cannot be flung
• Metronome has no effect
• Leftovers has no effect
• Pickup would be able to pick it up
• Tricking away an item doesn't make you use Pickup; you need to consume the item in some way
