Its really simple as well, and all you need is a toothpick and possibly water (toothpicks are seriously the best tool Ive found for altering after the actual paintbrush)
Some cards (mostly creatures) don't have any information at all in this area (not counting italics text, which we'll get to in a moment), which means they don't have any special abilities
// Hydaelyn, the Mothercrystal 6/8 Legendary Creature God Indestructible CARDNAME can't attack or block unless you control four or more other creatures
Lastly, the click wheel and Chocobo Edition card box are cool but minor additions that are unlikely to be worth much (though some click wheels end up being pricey)
Maybe somebody sideboards it in their Tezzeret deck against control
Now, before you get too excited, it's a fan creation so you won't find it in stores but this My Little Pony: Friendship is Magic: The Gathering card set is available to download for free
