Aside from lacking a way to draw cards on his own, hes basically the whole package
With a card, pin, and a playmat Winnie is getting a lot of love in this set
However, the comprehensive rules are meant to be the official way of playing the game
That's one of the wonderful things about trading card games: the game itself can actually be very accessible and easy, the strategy comes on all the cards and which cards you put in your deck and how you play them during the game
It's not quite clear why Battles were dropped - but from what Mark Rosewater's written in his article, it sounds like it has something to do with not being new-player friendly or accessible
It may not seem great at first, but it's a decent two drop for decks like UW (artifacts) RW (equipment, and BR (cheap spells), so I think it'll make the cut surprisingly often
