User blog comment:RiverToRue/Newish(?) Player here! Deck building advice and some general questions/@comment-11454852-20140925185906

Power averages for each size vary depending on the world, for example this 3 monsters: Demon Realm Warrior, Zepar, Systemic Dagger, and Armorknight Ogre. They're all Size 1 vanillas with 2 crit and 3k Def, but Zepar has 2k Pow, Systemic has 3k, and Ogre has 5k. Why? Because Magic World is less raw power more skill, Danger is high-power beatdown, and Dragon is an overall balance of stats.

As for ratios when deckbuilding, it is far less strict than in Vanguard since there's no "Grade stuck"-like risk forcing you to have a specifc type of card during the first turns regardless of the deck. Ancient likes more Size 3s, Magic likes spells and Size 1s, Danger likes more monsters, some decks don't want items or impacts, ect.
