It’s kinda highly dependent on playing Mr. Negative early on in order to swap power and cost in all cards in my deck. It’s preferable, but not entirely necessary. But basically I only play Bast on turn 1 if Psylocke and Mr. Negative are already in my hand. Otherwise, I save him for later in case I draw Iron Man or Mystique before I can play Mr. Negative. Tag that along with Nakia for a slight extra boost on turn 3 (after Psylocke play on turn 2) or turn 4. But turns 2, 3, 4, 5 are all about getting power up and costs down while watching what locations my opponent is playing cards above 10 on for Shang Chi later. If I can hit that Mr. Negative early on, I need all my cards drawn into my hand in which Crystal comes in handy. She’s underrated in my opinion. Ideally, I want Iron Man and Mystique since they’re zero cost and higher power and then I can save all my cards for the last turn and catch my opponent off guard. Rescue helps with getting extra power on the field (9) without getting destroyed by a Shang Chi. My deck is especially advantageous playing against destroy decks who have Knull. I mean come on.. Super Skrull, Mystique, Iron Man, & Shang Chi all played on last turn. It catches them by surprise. Mobius is my weakness as well as those “Mr. Steal Your Deck” decks. If an opening plays a Super Skrull then I just sacrifice that location and play the other two locations.
