Skimmed through Serebii's list of new Egg Moves for Gen 6. Didn't see all-that much that's interesting in regards to what Poke Transporter 'mons can bring to Pokes already available, but I did notice that Koffing has T-Spikes as an egg move now... which can be passed to Cofagrigus. A spin-blocker. QUICK, EVERYONE BREED A DEFOG DELIBIRD
Also, Tepig gets Sucker Punch. I certainly don't see Emboar ever showin' up in OU, but now it has priority and great neutral coverage with it's Fighting-type STAB, it might be higher than RU... ?
