The meatmaster pig in Hypixel gets speed when ridden, and is invulnerable to damage (has resistance 5) so it's meant to be something like a legit 0kb strat. I'm recommending that you recreate this in hunger games by giving the meatmaster pig speed 2 and resistance 5 (with infinite duration) when spawned, so it can serve the purpose it was meant for.

Also, on top of the resistance, it can't be hit by players and takes no kb.
