WHY ?

I'm learning to master/play a new archetype. Zoodiac! But I've been looking for a more practical way, in this case, playing against a bot and not online players. I need to practice, read each card, practice the combos, and play and play until I learn and master the cards. I've looked and haven't found one. Doesn't the game have a training bot? How amateurish! I start a casual online match, it takes me a while to make the combos because I'm reading the cards, and the opponent leaves the match/disconnects from the game, and I can't really learn/play. How boring, huh! ...
