Here's one I spent a little time on...
Got the images from here:-
http://www.skybluepink.com/products6.htmlCardsWhat I figure is you could make an animation for each card type... And set a skill, for casting linked to a variable on the common event to play each of the animations...
IE:- Skill Card Play - Anim "Magic casting" - Common Event "King of Coins"
King of Coins plays a skill anim called "King of Coins", hits the enemy for 1,000 HP and gives the caster £1,000 Gold
You could set this common event to play if the casters coins are equal or Less than 10Gold
