Soul Charge rule and regulation

Solitary Knight, Gancelot ability: When there's a "Blaster Blade" in your Soul, for that turn, this Unit gains +5000 Power and +1 Critical.

How do I get blaster blade to soul charged from a royal paladin deck?

How soul charge work?, every turn I can soul charge from deck?

Ride over it from grade 2 to 3 =D

Soul charge is just take the next top card of your deck and place it in the soul.

for gancelot's effect, its just as it states, when blaster blade in soul can use. soul is basically the cards underneath your vanguard so lets say you ride blaster blade over marron, marron is then in the blaster blade's soul. soul charge is just put the top deck into your soul thats all.
