Disney Lorcana's first set, The First Chapter, includes over 200 cards across six inks for you to brew decks, test out ideas, and get to grips with the game
To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as a flashback cost), add any cost increases (such as kicker costs), then apply any cost reductions (such as that of Cid's first ability)
I was concerned at first that it might be a little too dependent on getting to play first, as that extra turn to get a renown creature can be a really big deal, and I also had a few earlier draft experiences where every game was determined by rares, but as I play with it more I see successful decks doing a lot of different kinds of things
Mana Ramp I love having Reckless Barbarian and Patron of the Arts as Dragon cards that you can cast early to provide some temporary mana to power out a big Dragon, or maybe even The Ur-Dragon itself
