E.T.C. - Control/OTK Warrior - by Siberal

Combo:

the opponent must have enough creatures to allow the combo, or an enemy minion must have at least 5hp (to deal 30 damages to enemy hero face :))

E.T.C., GOD OF METAL + PEN FLINGER (on E.T.C.) + x2 BLOODSWORD MERCENARY (on E.T.C) + ANIMATED BROOMSTICK
then attack enemy minions, each attack will inflict 6 damage to enemy hero
(5 minions attacks (4 minions + 1E.T.C.): 30 damages -- 6 minions attacks: 36 damages -- 7 minions attacks: 39 damages)

It doesn't matter if E.T.C. dies during the attack, it will still activate the effect

Hints:
Go control and try to exploit risky skipper + armorsmith (x1 or x2) + battlerage to set board clear, card draw and a lot of armor,
a good board clear is risky skipper + lord barov or lord barov + bladestorm

AGGRO matchups - keep in order: risky skipper, minefield, armorsmith, lord barov or brawl
