"So what's the deal with power cards?"

[Burrito Al Pastor]

Why do we need a full deck of what our character can do when it's just as easy to scribble down the effects (with ALL modifications from feats, scores, magic weapons, etc.) on the back of the character sheet or a piece of scrap?

Short answer: if you find that's just as easy as cards... well, then, you don't really need power cards at all.

I suppose it must just be a matter of personal preference like you said. To me, there's nothing you can accomplish with cards that you can't accomplish (faster and using less printer ink) just by knowing your character well enough.

I could see the value of the cards being slightly greater the higher up you get in levels, though.

Printer Ink? I just use a pencil and color coded index cards. For example, my dragonborn cleric warpriest has a yellow card for his dragon breath, the racial power, reds for his channel divinity and paragon powers, and white for his normal ones. His rituals are orange. No printer ink, in fact, one pencil is great!
