I mean, I basically count...
1-2 Pansage (Beginning Set - confirmed in the news post), Simisage (BW-P Promo?)
3-7 Sewaddle/Swadloon (Black, Virizion Deck), Leavanny (Black)
8-10 Cottonee (Black, Virizion Deck), Whimsicott (Black)
11 Virizion (Virizion Deck)
12-13 Pansage (Beginning Set), Simisear (BW-P Promo?)
14-15 Darumaka, Darmanitan (Virizion Deck)
16-17 Panpour (Beginning Set), Simipour (BW-P Promo?)
18 Basculin (Black)
19-21 Cubchoo (Black, Virizion Deck), Beartic (Black)
I'm guessing they'll probably make a few exclusive Fire cards to quell the pyromaniacs, because otherwise this set will be very light on the red cards.
