Jevil

Haste, cascade, flash, trample, cascade
Jevil can do anything. (It can always attack,
block, be blocked, activate its abilities, be cast,
be countered, be destroyed, be regenerated, be
targeted, have a given ability, have its damage
prevented, deal damage, be made a wall by
Artificial Evolution, be cast, have +1/+1
counters put on it, etc. It's still not a player.)
