In the Clash of the Minions Tavern Brawl, all minions have Taunt and Charge.  The purpose of this deck is to reduce your health total to below 5 using Ice Block, thus reducing the cost of Molten Giant to 0.  After that happens, multiple copies of 8/8 Molten Giants can be summoned on a single turn using Molten Reflection, Echo of Medivh, and Youthful Brewmaster.  Since your opponent will likely have multiple Taunt minions on the field when that happens, Poison minions such as Stubborn Gastropod can help in clearing them.  Hitting Echo of Medivh on Brewmasters and Gastropods can be crucial in executing the combo.

I have experimented with multiple variations of this archetype for this Tavern Brawl, and I find the cards listed here to be the most optimal.  This is a fairly challenging deck to pilot, and it may require quite a few games to grasp its fundamentals.

Mulligan for card draw, especially Mad Scientist, as well as Ancient Watcher and Humongous Razorleaf to help you survive the early game.  While Emperor Thaurrisan is not strictly needed to deal 30+ damage, he can help in case you are missing certain combo pieces or don't have enough Mana to pull it off.  Emperor should ideally hit as many combo pieces (Molten Reflection, Echo of Medivh, and Youthful Brewmaster) as possible, along with Stubborn Gastropod to help clear Taunts.
