here is my deck to win against the heroic Gintfin. This is my first deck I made in HearthPWN, so please feel free to leave some constructive feedback .
Here a many basic cards in it because I wanted to make my deck as cheap as possible. I hope you'll enjoy it!
Here is what you have to do:
Seach for Animated Armor. This is the card which allows you to win against Giantfin, because he is pretty agressive and doesn't attack your minions. So he can make you only 7 facedamage per turn. Minimize the facedamage you're taking by playing Ice Barrier, Frost Nova, Cone of Cold, ...
And play Antique Healbot to restore your health.
Try to put minions with much attack like Core Hound or War Golem on the battlefield and attack Giantfin. DONT attack Giantfins minions, if you'll have an Animated Armor on the board! If you play Ethereal Conjurer search for freeze spells.
If there are any further questions, comments etc. you can easily write me a message and I'll try to answer it. If you like this deck please give it an upvote and I'll try to make some super cheap decks for the other heroic bosses in the league of explorers.
I wish you good luck with the deck, I won against him with the first try!
And sorry if my english isn't the best
