At maximum, his ultimate ability will quickly end the game once it goes off, though it is arguably a tad win-more
What I like about Kelsien, the Plague is that they dont force much direction outside of being one of your better options for a pinger deck
These are going to affect how Draft works forevermore (or at least until WotC changes things again!)
For beginners, you dont always need to spend your full budget on one booster box
This can throw off a multitude of strategies, and can even stun the opponent moderately , limiting him to a single card draw turn after turn
Each box will contain either Pokemon Red (Charizard), Pokemon Yellow (Pikachu), Pokemon Blue (Blastoise), Pokemon Green (Venusaur), Pokemon Silver (Lugia) or the special edition Team Rocket game
