Demenos, Caller of Terror

Flying, trample, vigilence
At the begining of your upkeep, create a 3/3
dragon raider token. If you didn't take damage
last turn, deal 2 damage to yourself. Whenever
you are dealt damage, you may discard a card or
sacrafice a creature. If you do, prevent all but
two of that damage.
You may pay Demonos' commander tax with life.
