but, if lets say you have a Cytoplast Manipulator and flicker it with Deadeye Navigator, then you lose control of any creatures that it may have stolen.
why is that?
not sure if this is supposed to be here, so if its in the wrong place, move it, please.
Creatures dying to having 0 or less toughness is caused by a state-based actions. State-based actions only check whenever a player would receive priority - they don't do anything while a spell or ability is resolving. Thus, although the Crawler briefly has 0 toughness during the resolution of Wheel, this is not 'noticed' by state-based actions, which only see it when it is a 7/7 again.
704.4. Unlike triggered abilities, state-based actions pay no attention to what happens during the resolution of a spell or ability. Example: A player controls a creature with the ability "This creature's power and toughness are each equal to the number of cards in your hand" and casts a spell whose effect is "Discard your hand, then draw seven cards." The creature will temporarily have toughness 0 in the middle of the spell's resolution but will be back up to toughness 7 when the spell finishes resolving. Thus the creature will survive when state-based actions are checked. In contrast, an ability that triggers when the player has no cards in hand goes on the stack after the spell resolves, because its trigger event happened during resolution.
By contrast, continuous effects with a duration, such as those created by Manipulator's ability, check to see whether their duration has ended continuously. No matter how briefly the duration-ending condition is met, they will end. (There's no rules quote I know of that explicitly states this, unfortunately.)
In short, just because there are two different sets of rules in operation, and they don't work the same way. Not a very satisfying answer, I know, but it's the only one there is.
Those are four completely different cards doing completely different things.
I think I see the confusion, though. You've run into the difference between static effects and state-based actions.
Cytoplast manipulator sets a control effect with a duration ends when it leaves the battlefield. The duration is a static effect that's always watching and can end at any time, it does not "wait" for anything else. When Cytoplast Manipulator it is exiled by the flicker effect it leaves the battlefield momentarily so control changes (the Manipulator that returns is a different object anyway).
It is true that Psychosis Crawler spends part of Wheel of Fortune with a power and toughness of 0. However state-based actions are only checked between spells and abilities resolving (well there are a few other times but the point is they're never checked during an effect resolving). Dying from damage or 0 toughness is a state-based action.
You can see a similar version of this same difference more easily with Lightning Bolt and Doom Blade. When you bolt a creature it takes damage while the spell is resolving and then after the spell resolves it is destroyed by state-based actions. When you doom blade the creature it goes to the graveyard while the spell is resolving.
It is actually the general rule that effects occur instantly when the game says so. State-based actions are the small class of things that are "cleaned up" later.
I recently learned that if you Wheel of Fortune while you have a Psychosis Crawler out, the Crawler will not die.

V. incorrect math.
2. quotes in signatures
III: irony.
there are two kinds of people in the world: those who can make reasonable conclusions based on conjecture.
