[Hearthstone + Warhammer. The Four Gods panic, the Emperor is stunned. Pure power fantasy!] Zhang Tian, global Hearthstone champion, died suddenly after pulling an all-nighter playing cards.
When he woke up, he had become a corporal in the Astra Militarum in the Warhammer 40K universe. The Chaos Fleet was chasing them down, the captain was shouting for everyone to blow up the ship, and a one-legged veteran beside him was getting ready to pull a grenade.
Just then, his Hearthstone card System activated
Zero-cost Arcane Shot: one blast sinks a Chaos frigate;
Two-cost Argent Squire: Divine Shield blocks a destroyer's main cannon all by itself;
One-cost Holy Light: purifies Nurgle's plague and burns hidden cultists to ash;
Three-cost Polymorph: an Inquisitor's henchmen come to arrest him and are turned on the spot into two bleating sheep.
A Plague Lord of Nurgle? He blasts it into oblivion with an Ice and Fire combo.
A greenskin Waaagh! boss? The five-cost legendary card Cairne Bloodhoof will show you what a Tauren war spear can do.
An Inquisitor suspects he's a Chaos Sorcerer? One Spellbender Secret will teach you a lesson.
The Chaos Gods hold frantic meetings in the Warp: This mortal is more villainous than we are. Maybe... we should just surrender?
