Rotface

Rotface is a legendary warrior minion card, from the Knights of the Frozen Throne set.

Strategy
Rotface is a soft taunt that forces the opponent to deal with it in two hits or fewer; as such, it's a great card to play in the late-game when both players are low on resources. If Rotface is killed in one hit, silenced, or the subject of a removal spell, then the 4/6 stats for 8 mana is a terrible deal, and can be a large setback.

Legendary minions have a huge disparity in quality, with fantastic results (such as summoning a Tirion Fordring or Tyrantus), as well as a lot of very poor results (such as Patches the Pirate or Bloodmage Thalnos). For this reason, it pays off to maximize the amount of value you are getting from this card.

Utilizing self-damaging effects such as Whirlwind or directing an effect like Slam at Rotface can help generate extra value from the card's effect, going beyond what you could normally get from strictly trading with him. Equipping a Blood Razor prior to summoning Rotface, decreasing its durability to 1, and then performing an attack with it after summoning Rotface is one easy way to trigger his effect risk-free. Having Animated Berserker on the field prior to summoning him will also have this effect. Scourgelord Garrosh also has excellent synergy with Rotface, as his Hero Power provides an efficient way to trigger Rotface's effect.

Buff cards such as Rampage also work well with Rotface, allowing him to perform extra trades and generate more minions.

Rotface can be very powerful in Arena thanks to the difficulty of removing it in one go. If you're able to successfully bait out removal spells prior to playing him, he can easily win the game on his own.

Note that when Rotface takes damage from a minion with Poisonous, he will not summon a minion prior to dying.
