Heroic Giantfin's deck has 50 cards instead of the usual 30.

Strategy[edit | edit source]

This is a fairly straightforward fight. Giantfin will summon a large number of Murlocs, which are mostly weak but with the help of the usual synergistic Murlocs can grow in size. However, the main threat is Mrgl Mrgl Nyah Nyah (Heroic) and Anyfin Can Happen, each of which can suddenly threaten to overwhelm the player. Note that several of Giantfin's Murlocs have Charge, making them able to attack immediately after being resurrected by one of these effects.

At the start of each turn, the boss' auto-cast Hero Power Mrglmrgl MRGL! (Heroic) will try to draw additional cards; in Normal mode the number is dependent on the size of both heroes' hand, making it a good idea to keep yours fairly empty.

Normal[edit | edit source]

Since the boss draws every turn until he has the same amount of cards as the player, it's useful to keep your hand as empty as possible. Therefore it's recommended to play an Aggro deck with lots of cheap minions that can fill the board and keep the hand empty early. Examples include Zoo Warlock, Aggro Paladin and Face Hunter.

Heroic[edit | edit source]

An easy way to beat Heroic Giantfin is to use a mage deck full of AoE cards: Neutral minions that play into this strategy include Explosive Sheep, Unstable Ghoul, Abomination, Tunnel Blaster and Primordial Drake.

Spells include Shooting Star, Arcane Explosion, Flame Ward, Flamestrike and Blizzard. They can be improved by minions with Spell Damage as well as combined with Flamewaker to remove minions with bigger health values.

Since the boss possesses many Murlocs in his deck Hungry Crab will fit perfectly in the strategy.

The main goal of this is to hold the boss minions as long as possible until he has reached fatigue, since Giantfin obtains 3 cards per turn from Mrglmrgl MRGL!, his deck will be out of fuel pretty fast even possessing 51 cards in Heroic mode.

Coldlight Oracle and Research Project can speed this up. At the same time this card can also burn the enemy cards by making the enemy hand full if played early; this tactic becomes even more effective with Frost Nova since the boss can fill his side of the board pretty quickly.

Bringing Counterspell can block the enemy revival spells, and, if it counters Anyfin Can Happen, Giantfin will have lost almost his entire turn. Ice Block and Ice Barrier are other useful secrets that can stall the game for the player. To bring out these secrets with tempo it's wise to bring Mad Scientist and Arcane Flakmage.

Since you want to stall the game and most enemy minions are low HP it's useful to bring Taunt minions with low attack but high health values. Examples are Deathlord, Ancient of Blossoms and Mosh'ogg Enforcer. The boss will have a hard time getting through these minions.

Dialogue[edit | edit source]

Before match

Sir Finley Mrrgglton
Alas, I’d hoped to avoid Giantfin. Ah well. For glory!



Turn 1

Mrrrgl! Mrrglrrglmrgl
Sir Finley Mrrgglton
Really now? That’s terribly rude.

Mrgl Mrgl Nyah Nyah (Heroic)

Mrrrglmrrrgl Nyah!
Sir Finley Mrrgglton
Oh pish posh. Don’t be childish.

Emote Response


Play Old Murk-Eye

Middlefin, what are you doing here?


Sir Finley Mrrgglton
A shame. With a better upbringing he could have been a decent sort.

Unused[edit | edit source]

The following dialogues were included in the game's strings, but do not appear now.

Turn 2

Sir Finley Mrrgglton
My brothers, work with us! We don’t have to fight!
Sir Finley Mrrgglton
I suppose that was to be expected.

Dead murlocs

Sir Finley Mrrgglton
So many dead. Such a waste.


Sir Finley Mrrgglton
I grew up a Tidehunter before Elise found me. Would this have been my fate?
No, Finley! You were different even then.

Lore[edit | edit source]

In League of Explorers

Giantfin is original to Hearthstone.

If Old Murk-Eye is played during the Giantfin encounter, Giantfin responds "Middlefin, what are you doing here?" This suggests familiarity, possibly even a familial relationship between the two; note the scale of Tinyfin, Middlefin, Giantfin and possibly even Megafin.

In World of Warcraft

Giantfin later appeared in World of Warcraft as an elite mob, during the Un'Goro Madness micro-holiday. Like the other elites, he possessed the ability to gain various "Adapations" granting him special buffs, and dropped a "Dino Mojo" consumable upon death. His abilities included summoning an army of murlocs to defend him.

Trivia[edit | edit source]

Giantfin was the first original Hearthstone character to appear as a boss in World of Warcraft, and only the third in total to appear in the game, following Sir Finley Mrrgglton and Morgl the Oracle.
