We recently received rulings from Konami for this situation.
Question:
Is sending the 4 Crystal Beasts from my Spell and Trap Card Zone a cost to activate "Cryatal Abundance"?
Can I activate "Crystal Abundance" while "Dimensional Fissure" is face-up on the field?
If I activate "Crystal Abudance" while "Dimensional Fissure" is face-up on the field, what happens to the 4 Crystal Beasts?
Answer:
Sending 4 Crystal Beasts from your Spell and Trap Card Zone is a cost to activate "Crystal Abundance".
Yes, you can activate "Crystal Abundance" while "Dimensional Fissure" is face-up on the field.
If you activate "Crystal Abundance" while "Dimensional Fissure" is face-up on the field, the 4 Crystal Beasts sent from the Spell and Trap Card Zone for the cost will go to the Graveyard.
