Battler of the Twin Brush, Polaris
At the end of the battle that this unit attacked, by paying Counter-Blast 1, you can give this units power to one rear-guard! Afterwards, if that rear-guard's power becomes 50000 or greater, you can stand that unit too! If that rear-guard's power becomes 70000 or greater and your opponent's vanguard is grade 3 or greater, you can stand this unit and this unit gets +15000 Power! Focus on powering up one rear-guard to power of 50000 of greater! As the power that this unit gives includes the power of the unit that boosted it as well as the power from triggers that are applied to it, by powering up your vanguard, it'll also make it easier to power up your rear-guards!

Ambers Triangular
During your turn, if there are no ally rear-guards in the same column, this unit gets +10000 Power! When its attack hits, you can give one of your rear-guards +10000 Power! By calling this unit on top of an Accel Circle, its power will become 27000 or greater, making it easier to reach a power of 50000 or greater! As it has an ability that is capable of powering up other units when its attack hits, it can be a great help for powering up when you have multiple copies called onto the field!
