Game Mechanics:
Spoiler
Soul: The Soul is a Recource in Buddyfight, it is normally used for Soulguard. The Soul of a Monster can be inherited by another Monster if its Call Cost "Put this card on top of a monster on your field with "(Archetype)" in its card Name" if the sacrificed Monster still has Soul.
Soulguard: allows monsters to avoid leaving the field (destruction, returning to hand, ect.) at the cost of discarding a card from the soul of that monster.
Counterattack: If Monster with counterattack are still on the field after being attacked (due to soulguard or due to higher defense) you have to destroy the Card that attacked the Monster if its defense is less than the power of the Monster with Counterattack. If it was a Link attack you may only destroy 1 of the attacker(items can not be destroyed by Counterattack).
link attack: when you link attack you attack the Opponent or the opponents Monster with 2 or more Monster and/or items. The link attack has the combined power and critical of the Cards that link attack. You cannot link attack with an item if you have a Monster in the Center. Link attacks cannot be performed on the first turn of a fight.
Double/Triple Attack: a Monster with double/triple may attack two/three times per turn. You may not attack more than once on the first turn of a fight.
Card Rulings:
Spoiler
Jackknife Dragon
-if you call another Jackknife with this Cards skill you don't Need to pay the call cost of the called Monster(Jackknife still goes to Soul even if the called doesn't have soulguard).
I will add more with time.
