There are multiple ways to Special Summon Dark Flare Knight by using Cyber-Stein. One is to use cards that can gain you Life Points like Enchanted Javelin, Solemn Wishes or Aegis of Gaia until you have enough Life Points to pay the cost. Another way is when your Life Points reaches 1000 or below, you can use Tea's Skill Life Cost 0 which lets you to not spend Life Points when activating a card effect. And one more way is by using LP boost β/LP boost γ which adds 1500/2500 Life Points at the beginning of the match, but it reduces your starting hand by 1/2 cards.

I think that the main thing holding this card back from being a good alternate in a dm style dark pally deck is the fact that you need to slot in the mirage knight itself, if the mirage knight was summoned from outside the game, it would be way better imho
This. I still don't get why they made this card and Mirage Knight as weak as they are.
It would be convenient if its effect activates while being destroyed by card effects. You have to force your opponent to attack it.
You can use The Dark Hex Sealed and Dark Magician to summon it w/o Polymerization.
