How can I defeat Majordomo Executus?

Solution 1:

There are a couple tricks you can use to make life a little easier against the majordomo and his master.

1: Perhaps most importantly, keep your damage back. If he's above 20 HP, he can't summon Giants, if he's at 16+, he can only summon one per turn. Build a board and/or hand full of burst. 1a: Alternatively, play Warrior, get him low, empty his hand of giants, and Brawl.

2: Abuse his 1/3 summons. Grim Patron is especially good at this, Frothing Berserker, Acolyte of Pain, and Enrage cards are also strong.

3: If you can burst him into Ragnaros form, you should probably do it. 8 damage to a random target usually isn't that bad, and once he turns into Ragnaros he can't cast Molten Giants, which are his scariest creatures. (This tactic may backfire if your board is only a couple strong creatures)

4: Don't use Hunter, you probably CAN make it work, but 2 damage to face hero power, and very limited removal don't help in this fight. You'll be better off with any other class.

Solution 2:

Note what the gimmick of a molten giant is. Its mana cost lowers for the amount of damage the hero has taken.

So, for Majordomo Executus (ME) at 30 health, it'd cost 20 mana.
With ME at 20 health, it'd cost 10 mana.
With ME at 10 health or below, it'd cost 0 mana.

The lower ME's health is, the more giants he can play.

Now here's another trick: Ragnaros only has 8 health. Which means he can take a MAXIMUM of 7 damage (ignoring armor, since molten giant text also ignores armor). That means that for Ragnaros, molten giants AT LEAST cost 13 mana (impossible to play).

My strategy was as follows:

• Keep Majordomo Executus above 20 health, but make sure you dominate the board. Keep building the board, until you have enough damage to kill him (I'm assuming here that the minions you use for that are still alive when Ragnaros enters the game). This way, both ME and RAG never managed to play a molten giant.
• Once RAG hits the board, just make sure you haven't put all your eggs in one basket (more appropriately, all attack on one minion). Rag might kill one every turn with his hero power, but only one per turn. You can still use the others to beat his face until he dies.

The trick here is to not dramtically wound Majordomo Executus until you have enough board advantage to steamroll both him and Rag.

Solution 3:

To beat the heroic one i used a spinoff of the Shaman hyper death combo dek with baron rivendare, ancestral, reincrnate,sylvanas, and kt. U wait until you build a big kt sylvanas board then drop his moltens, and then take them all and kill him. The kts render rags hero power irrelevant. Worked first try.

Solution 4:

I won with this deck. Of course, you can change it a little bit.
