Released in the final set of TCG cards, Demon of Might is undisputably the most powerful version of the Balrog ever printed. With an innate Damage + 2 and Fierce, is causes pain to even well-prepared Fellowships, but its real strength lies in its text. The fact that is skips the maneuver phase while underground is extremely potent; it prevents followers from being used, stops several versions of The One Ring from being equipped, prevents maneuver wounding and serves as a counter to Madril, Defender of Osgiliath. This card can also be played with other minions if your opponent floods the twilight pool, and will protect them all from maneuver and archery wounding (Both of which are common in the Expanded format.). This Balrog is not the first to prevent assignments to low strength characters, but this ability is also handy, as it forces the opponent to sacrifice important companions to it. Combine with Cavern Entrance to deny your opponent even more effects.
