Wow game changing is right. The best part is, the only way to protect this from PC would be to use butterfly effect after it had been played. So any deck with PC need to worry about their spells.
After looking at the list of abilities, here's some suggestions:
- Mitosis, Kill all other copies of the target card OR Kill a random copy of the target card
- Freeze, Freeze your weapon OR Cast immortality on the creature
- Ice bolt, Give 2 purify counters to the target per every 10
. May freeze the target.
- Nymph's Tears, Target becomes a pillar / tower of its element. (Tower depends on whether it is upped. Other creatures give Quantums)
- Dry Spell, Cast flooding for a turn
- Holy Light, Damage the target for up to 10 HP. Heal if the target's element is
or
- Blessing, Inflict 3 poison counters to the target creature
- Luciferin, All creatures with a skill lose it and gain "bio-luminescence"
- Flying weapon, destroy your weapon OR Fly opponent's weapon OR Play a dagger
- Shard of Readiness, Add 2 quanta to the cost of the creature's ability. If target is
, lobotomize. (Quanta added is the same type as current or of card element if the ability uses other quanta or is free.)
Just thinking about how some of those would work is mind boggling
