Now I'm going to take this game, and turn it into a minecraft version instead of pokemon.

Rules:
Each minecraft mob starts off with 50 HP.
Player chooses 2 mobs from the list below.
Player subtracts 10 health from that mob, then adds 10 health to another mob.
This game is YPPY, so no posting until 2 other people post before you. No double posting either.
The winner mob will be crowned the best/strongest mob in all of minecraft! So make sure your mob wins!
There will be 3 rounds and 2 groups:
1st round all mobs appear.
2nd round first 3 losing mobs will be gone.
3rd round only top 2 mobs will remain.
The 2 groups are Hostile mobs, and Passive mobs.

Bolding, Underlining, and Italicizing are optional. Just so long as you say that you healed/damaged it, so we know which 2 you're targeting.
