The great game of UFS has so many cards in it that deck building can sometimes be really hard. Especially when you want to try something new and really anti-meta. The slots in your deck are so hard to trim and cut to fit in new cards or add in a new style. This is the hardest thing I face, and most of us probably, with deck building. With that said trying new cards that are powerful and different from the "staples" can be a great skill to have with your deck building and can really throw other opponents off guard. I for one will never forget the first time I Dark Hearted a Promo Alex after he formed to draw. The look on my opponents face was more priceless than a credit card commercial.
