This is exactly the kind of moment Skolnik meant when he talked about emotional resonance not spoiling the scene, but letting the mechanics make you remember it
Having to discard a card every turn doesn't matter when you're drawing multiple a turn thanks to Sythis, Harvest's Hand, Mesa Enchantress, or Argothian Enchantress
This card can be attached to a Pokemon, and once the Pokemon is attacked, 20 damage will be dealt to the attacker
If this card is Pendulum Summoned or sent to the GY: You can target 1 "Zefra" card in your Pendulum Zone, except "Shaddoll Zefracore"
The trigger for dealing combat damage to a player is a cool Divination combined with a fling to the face
It gives you a lot of options and is far less of a cost when you don't use it than it is for other decks
