Snowgal deck contains Fang of Light, Garmal and a lot of snogals..
The combo for this deck is to have:
-Fang of Light, Garmall as Vanguard
-Have all 4 snogal on your field to pewer-up your snogals and Garmall
If u have all 4 snogals on field,
Garmall's base power = 10k + 4 x 1k = 14k
Snogal's base power = 6k + 4x 1k = 10k
So if u can make all the snogals as rearguards (not as Vanguard booster).,
u can attack opponent with total power of 20k..!!
That's 15k shield wasted for 10k Vanguard.!
The thing that u have to be careful of is to not lose any snogal.. if u lose them, Garmall's and other snogals' base power will drop.. So., as the anime suggests., don't use snogal deck against Kagero clan..
