For the Boss Task, could you make it a little bit clearer by what you mean by "fieldwipe"? Is that just saying AoE that affects both sides? Because I doubt you want six submissions of "all creatures on the field die, drain all remaining quanta" type of card.
For example, would a card like this be a valid submission? It doesn't necessarily wipe the field. There's no guarantee that creatures will die at all.
Fieldwipe: Remove all creatures from the field.
Fieldwipe: Remove all permanents.
Fieldwipe: Deal damage to every creature.
Fieldwipe: Clean the field with a damp cloth.
Fieldwipe: Erase the field's memory, leaving it susceptible to psychological manipulation.
Fieldwipe: Wipe the left side of the field, pushing everything to the right.
Fieldwipe: Wipe each card, leaving them dazzlingly shiny and blinding your opponent.
Fieldwipe: Wipe the stats off your creatures.
Feeldwipe: Run your hands over Dwipe's muscular legs.
Fieldwife: Propose to and marry the field.
Everything is open to interpretation!!! Do what you want, but if it's not obvious, tell us how it's related to fieldwipery in your submission.
