Need help Remembering a card's name
I can't seem to find the card. I thought it was a blue enchantment card that cost 6. I know it was not a creature. It had text that said something like you can tap other enchantment for mana or to help pay for spell. It was not a waterbending, improvise, or convoke card.
It is not:
Arc Reactor, Gene Pollinator, Cryptolith Rite, or Inspiring Statuary.
