Just played a very entertaining hearthstone battlegrounds game.
[ATTACH=CONFIG]6038[/ATTACH]
The three birds on the left trigger the deathrattle of a friendly minion
The demon in the middle gives its max health to other friendly minions as its deathrattle
The dragon makes any enchantments/buffs it receives during combat permanent
The second to last minion makes deathrattles trigger twice.
Quick Explanation:
The bird triggers the demon's deathrattle, this gives a bunch of health to the dragon, the dragon is now permanently buffed.
The hero I am playing has the ability to swap the stats of two minions as its hero power, in other words each turn I swap the stats of the demon and the dragon - creating a very, very quick scaling system.
From the mess that was my screen it's difficult to decipher the health of the dragon (?03,852,749 - hundreds of millions for sure but unclear on the first digit), what I can tell is that the demon's health is 97,864,038.
The game I was playing had murlocs banned and no one playing beasts in the end game, in other words it is very difficult to get a poisonous minion so most people rely purely on having higher stats than others.
Given that my opponents had minions at around the 50/50 to 100/100 size, they didn't make quite the impact they were hoping for :D
