how about... "The 3rd Great Egg Swap is here and live for GT8, and this time it's the Summer of Swappage! Breed one egg (the more exciting the better), then swap with it someone else's egg for a point. Keep swapping with as many people as possible for more points! Plus - at the end you get a brand new mystery Pokémon to play with! What are you waiting for?"
"An event for those who love to breed eggs and trade them. This event involves trading between the Generation 5 games, Black and White over the Nintendo Wi-Fi Connection. Be prepared for the battle of the eggs!"
