User blog:KrystalLBX/20 damage challenge (OTK puzzle)

Alright so here is how this works, you must deal 20 damage in a single turn

Your opponent's field/hand

No center monster or card capable of redirecting attacks

Nothing that can nullify your attacks

And of course they have 20 life

You have 3 gauge (After your charge draw) and 5 cards in your hand. You are running Dungeon world and your deck consists of 0 demon lords in it's build and you don't have any dangerous fuse/golden treasure boxes in your build.

With the above scenario, how can you inflict 20 damage in one turn?
