Benthic Bloom

At the beginning of your upkeep, put a void counter on this artifact. Then you may exile a nonland permanent you control. If you do, reveal cards from the top of your library until you reveal a card that shares a card type with that card with a greater mana cost. You may cast that card without paying it’s mana cost {1}{B}{T}: move all void counters from this artifact to target permanent you control
