Thank you for posting this. It was interesting to get to see Academy in action. I'm looking forward to getting to play it once it comes out.
My feeling is that the Wizard needed to focus more on using stagger to lock down the Razortusk, not play the weapon until later, when he might actually use it with some consistency, and do more to defend his Lightning Raptor. In addition, Shrink would have really shut down that Razortusk for a few rounds. Badger Frenzy is a lot less exciting when it's 2-3 mana for 2 attack dice instead of 4 dice. I like the idea of a Giant Size on Lightning Raptor to discourage attacking him and make his attacks more relevant earlier, but it helps to reveal it.
On the Beastmaster side, I liked the use of Joined Strength and using Badger Frenzy to deal a ton of damage and end the game at the first opportunity. I'm not sure how good that will be against a good stalling Wizard that uses guards, Shrink, repeated stagger conditions, and maybe Exile to bog you down, but I'm looking forward to finding out. My main issue with Badger Frenzy in Academy is that there is only 1 creature I would actually want to use it on in Academy, and if my opponent locks that creature down (and they'll want to), it loses a lot of value.
