Fire's Master

Mountain walk, vigilance, flying, trample, haste, indestructible. Whenever you draw a card or play
a card Fire's Master deals 1 damage to all
opponents. It can't be countered or avoided even
by hexproof. Red creatures you control gain
trample, haste, and +7+7. Planeswalkers you
control can't go below 7 loyalty even if their abilities or damage they receive would cause it.
This means you can use minus abilities without
losing loyalty. They must get to 7 or more loyalty before this would apply.
