So, Animalgirl. This one has been in the works for a while, but it's taken some time to get it right. The core idea is that your transformation has three different aspects to it, Bunny, Cat and Puppy. Unlike other transformations which have a singular mechanical focus, in Animalgirl you have to balance these three different paths. This is done by investing in the different aspects of Animalgirl. In Animalgirl, the permanent buy pile cards are replaced by the cards you see at the top of this post. Buying these cards don't add anything to your deck, rather they give you bunny points, cat points or dog points.
What Animal themed cards you get dealt are based on these points, not your TF level. Because of this, all Animalgirl cards can be bought with any resource. Now, let's take a look at the individual animals.

As a Bunnygirl, you like nothing better than to fuck all day long. This is represented by the aspect being Heart focused. By going down the Bunny route, you're specializing in resource generation and being able to buy powerful cards faster.

The Catgirl meanwhile wants to deal as much TF as fast as possible. Accumulate Cat points and you'll be able to build a more aggressive deck than any other TF has been capable of.

But maybe being aggressive isn't your style. If you prefer the safety of a loving master, try the Puppygirl. This aspect is all about defense. Set up an impenetrable wall of love and big sloppy puppy kisses.

Or maybe you want to go all three at once! The choice is up to you.
