Poaobiec is playing the game much the same way, and for the same team, as PapaD. They are not controlled opposition, but poisoned wells. Controlled opposition implies they are resisting and compelled by some means.
What many should consider is the idea that their turn can still be "my" play. When I know what cards you have available and the current state of the game, I know what you absolutely must play in order to shift the game in your favor - and if I have control, then the choice is ultimately futile as all plays that can be made either have a counter, fail to change the game status, or make the game worse for them.
Blue plays from the library a lot.
