Yeah Spark makes this tougher. The other 0 costers not as much since dying at the end of the turn is part of the point (would serve as either a death enabler or fractal/eclipse beater not both at once). I could go 1|0 and 2|0, making it a 3|1 4|1 with eclipse.... Would be weaker without eclipse but tough to balance, especially since I'm not looking to enable a deck that uses both this and Ball Lightning in a rush. Will have to give it some thought, maybe sacrificing the simplicity for an ability... Perhaps:
When this dies, generate a copy of it without an ability?
