Power Giant from the coming Booster

By discarding 1 Level 4 or lower Monster Card from your hand, you can Special Summon this card. Afterwards, this card's Level is decreased by the Level of the discarded monster. During your Battle Phase if this card attacks, all Effect Damage to your Life Points is negated.

is a good card in supporting synchro by decreasing monster's level..
second is the attack is high compare to the other special summon monster like:
Cyber Dragon,Vice Dragon...
its attack is 2200 but the weakness is defence 0...
extra effect behind is MAD....
in battle phase all effest damage to life point is negated!!!!!!!
