Lets take a look at two cards from CCCs past that have used simple templating to deliver powerful results
Psychic This attack does 90 more damage for each Energy attached to your opponent's Active Pokmon
Since we need this card to work in every circumstance, its basically reserved for decks with high levels of redundancy, which is French for reanimation decks
Stick with simple choices for your first design to keep things simple, like a mouse, chicken, snake, tree, ice cube, or a feather
These best cards are all about fun and flavor with a sprinkling of aesthetic flair
If you have a large creature with trample that is attacking, cast this and potentially draw 5+ cards
