The game wont let me summon cyber dragon if neither player has any monsters and it wont let me summon power invader in the opponent has 2 or more monsters

Cyber Dragon's inherent Special Summon requires both that you not control a monster and that your opponent does control a monster.

Power Invader works for me.
