Allies are a big part of Cosmic Encounter. Who to invite, who will accept, who you trust not to stab you in the back? The Human is an excellent addition to almost any side. The ability to add 4 to your side's total power can be powerful, but the Human really shines when his side can zap his power. Holding on to a zap until you can invite the Human can pay off big, especially if your opponent drops a 40 card.
