I thought this was pretty obvious, but I deliberately avoided spells that were already available on sticks. That includes antimatter (Nymph) -- and in fact ALL of the Alchemy cards, for the same reason -- and Mutation (Elf/Druid), Plague (Retrovirus), etc. Also, I didn't want to just spam all of the various Bolt/Lance cards because that's boring. I had to choose Ice Bolt because Water's only other spell, Congeal, is already available on a stick (Octopus).
For those reasons,
would be limited to Rain of Fire, Detonation, and Cremation as available choice.
only has Steal and Drain Life, and Drain Life is a Bolt, so it has to be Steal.
I'm OK with some of the stronger spells costing significantly more to conjure into your hand (whomever said these were anti-deckout cards please note that they don't appear in your deck, they appear in your hand) -- say, 7 to conjure an RoF and 8 to conjure a Steal?
I'm honestly not that sure about the brokenness of repeatable Steal, though. Short of SoGs, there's a lot of circumstances when Steal == Deflag because you don't have the quanta to use something, or Steal is just plan bad because you want to keep your current weapon/shield/whatever.
