20 Fleas appear in unprotected backline.
Condition: Don't use cloaks and fastest possible guaranteed kill time.

If Fleas was the answer:

Move bonus: (used spider)
Condition bonus: (did not use cloaks)
cheap
easy
fast

.. First answer so it wins so far.

If Swift was the next answer:

Cheap +4 = Costs less to kill Fleas
Easy -3 = Less easy to use than Fleas
Fast +2 = Faster than Fleas (required build time + movement)
Speed Bonus +3 = Air gets a better speed bonus
Condition -5 = Less reliable kill time due to cloaking Fleas

Total Points = 1 (+4, -3, +2, +3, -5)

Thus, the score is better, so the Swift becommes the winning answer; if it is not debated
