Erm actually, you had gold and enough blocks so. You can make a spawning platform and wait for piglins to spawn, in that case you have a chance for them to trade you a fire charge (8.7% for one gold) and you have 30 gold So you would have about a 261% chance of getting a fire charge (so you could trade about fifteen and still have a 100% chance) So TLDR: make a spawning platform, wait for piglins, and trade ur gold for firecharges.
You sound pretty young so I'm honestly impressed with your editing and cinematography skills. If you're an adult I apologize for assuming, but seriously, You've just earned another subscriber. Keep up the good work! 👍
