Allow me to explain... *a chair pops up under Pen*
It's really quite simple, in the cardgame, that is, Capcom vs SNK Card Clash, each card have BP and SP. Now, you ask, what are these numbers? Simple, the BP of a card is how much damage it can take, as well as how much damage it delivers. So, if... let's say one card with BP 700 attacks another card with BP 400, the card with 700 would win, but not before the card with 400 subtracted 400 BP on the 700 card. This is a combat round.
SP is Special Points, and works this way. Action cards, cards that can do special things and are not Character cards, costs a certain amount of SP to play. If you place a card with +3 SP on the table, you (the player) adds 3 SP to your SP Pool. This only works once for every card.
There, and that is why we know that the Earth is really banana shaped.
