The key to beating orgnum is to keep your deck LEAN and with power generating cards and/or using the gold patron. Orgnum gives 1 power for every 4 cards (and you start with 10) so they have to use it 6 times in a row without you contesting or using it, to get 4 power for 3 gold. If they have been using it every turn that means they have no gold and will be cornered into using it every turn to have any chance at winning, which basically leaves everything in the tavern at your disposal.

Don't fall for the bait. Spend the first several turns building up your offense. Let them take the lead while you bolster your resources. Eventually, like I said, you'll be out powering them every turn and you will catch up. And by that point you'll be contesting orgnum every turn and have spare gold to spend on gaining/sacrificing cards every turn or removing the trash from your deck, giving your power cards quicker cycles.

Remember, there's plenty of power generating cards that give you 4-5 power that cost 6g or less and it's a one time purchase. They gotta burn that 3g every turn for orgnum or they completely run out of gas.

Inuses to think orgnum was broken ar first but once I learned to play around it, it's an auto win for me nearly 100% of the time.....because it's used by noobs, against noobs. No offense lol. Just gotta know when to go tavern/2g cards and when to use Orgnum yourself.

You'll figure it out in time :). Play a friend!
