Darkness cannot drive out darkness; only light can do that.

—Martin Luter King

Yellow is the valiant and holy color of knights, dragons, and wizards; it's the opposite of black, which stands for darkness, monsters, and demons. Yellow is also the ideal beginner deck-- it's easy to use, average in all aspects, and has a healing focus (this allows beginners to survive longer, theoretically raising the HP limit). It also has several cards (Orb of Potency, Exogenerate, Energetic Wizard, etc.) that are low-cost yet a huge help, letting the player stay ahead of the energy curve. Whether you're a new player or an experienced one, yellow provides many opportunities that other colors cannot.
