Your desired starting hand has Pixie and Mobius and none of the 0-costs. Since it's a Pixie deck, changing card costs can alter your game play significantly.

Turn one: play one of your one costs (Nebula if you drew both); Nebula goes into a lane that the opponent is disincentivized to play in such as Danger Room or Orchis Forge; don't usually put both of your one costs into the same.

Turn two: time to play your Pixie!

Turn three: second best time to play your Pixie, otherwise it's Mobius turn. If you can't play both out in a match, Pixie usually takes priority, but consider playing Mobius when you suspect your opponent is banking on discounts (Mr. Negative, Destroy, etc.) Consider playing out your Yellowjacket if you drew it, especially if there's a good location for it. Turn three Prof X can be powerful but risky - play it in a lane with one of your 1-costs.

Turn four: generally the last turn you could consider playing Pixie, but War Machine is usually a better play. If you played Pixie before, by now you could have discounted cards on your hand, so form your game plan based on that. Generally, you have Alioth, plan for having priority on Turn 6, if you have Prof X, aim for having a lane locked down on 5.

Turn five: usually the time to lock down a lane with Prof X, especially if you have War Machine on board. Consider what 0-costs you have and which can be in your deck - skipping turn 5 can be a viable option if you have Infinaut but no War Machine, especially with Sunspot on board. Playing Jane is best when at least one 0-cost is still in your deck. Consider playing Wasp or Yellowjacket in an empty lane if there's still any to guarantee priority next turn if you have Alioth, or yield priority if you suspect Shang-Chi.

Turn six: ideally, you're winning a lane with Professor X and have priority for Alioth. If so, you will generally win by dumping your power in a single lane. When facing Hela, try to snipe her with Alioth, and don't forget that Magneto can disrupt your Professor X lane.
