I'd take a lot of things. Adamant Entei, shiny Timid/Modest Charizard, any legendaries/events/mythics, 6 IV Pokemon, etc. I also have 2 Enteis that I'd be willing to trade, but I didn't catch them.
EDIT: Want to make sure you know the 4 legends are from Pokemon red, not gen 6.
As long as legit, That is fine.
I can offer mythical pokemon, I have all 20th anni/diancie/hoopa/volcanion.
Wouldn't mind one of the Entei...as long as legit, sir.
