Collection Power you gain by holding cards. The value of your collection power is equal to the amount of DEC you gain by burning your card.

DEC - Just DEC holding in your account.

DEC Liquidity Pools - I don't understand quite well, but I think there's some liquidity pools on CubDefi, Tribaldex or something like that.

Card Packs - Holding some kind of card pack in your account.

Land Plots - Holding a plot of land in your account.

Champions Points - Reaching Champion League in a season gives you champion points.

SPT - Holding Splintertalks.

Card Skins - You can buy Skins in the Splinterlands website, that gives you points.

Totems - I don't really know.

Titles - I think that you need to reach some achievements to earn a title, like buying 100 packs on pre-sale (just an example). Most titles that there are right now were given to the old players that were very early into Splinterlands and have a lot of assets (I might be wrong about this).

Hopefully that has helped you.
