I made this deck a while ago, so I don't ALL the way remember it, but this is the basic idea:
Use gravity bind to stop and invalidate many monsters.
Activate cauldron of the old man to gain TONS of LP, and deal out plenty of damage as well.
Use child's play to gain more LP, while making your monsters untouchable when working with cauldron.
Use pyro monsters to work together creating a chain of damage.
Since raging flame sprite is a three star it can attack regardless of gravity bind, and attacks LP directly, doing more damage over time.
Summon lava golem to your opponents field, dealing 1000 damage every turn.
With this combo, you should be relatively untouchable, while dealing a good amount of damage each turn. Plus, with gravity bind, you can constantly gain LP, while being able to switch freely to damage!
Hope you like the deck :) leave advice in the comments.
