Hi there splinterbuddies. This is my entry to this week's Battle Mage Secrets Weekly Challenge - Fab Four. This is a recently added rule to the game so I am still getting use to it.Fab FourUp to four Units can be used.So you see, this is just limiting the number of monster cards you can summon from 6 units to 4 units. This is going to affect your strategy of course because normally you are considering your team from a summoner to six units of summoned monsters for the medium and high mana battles mostly, but with this ruleset is being added to the family, you have another thing to consider with what you will use in your batlle strategy.So you see, this is just limiting the number of monster cards you can summon from 6 units to 4 units.
