Whooo!! That's so great! I know the feeling, happened to me once or twice! Congratz!
You're doing great! We all started somewhere, without Champions, without Diamond, so don't worry. My advice: save gold for atleast 5-7 ultimates. Save them till the first Champion-tournament. There is a way you can calculate the odds you have in advance for the whole tournament. For example, I know in this tournament, I have 15% chance against round 20, and 10% chance against round 25. If you use ultimate in low-chance rounds, you can calculate if you have enough gold to get you finished. Then, the Champion you've won will help you greatly in new tournaments so you need less and less ultimates.
To be honest, I have 7 Diamonds, and 9 (or more, I don't count anymore) Champions, but I still use ulti on those low-chance rounds, for I don't want the stress of loosing time after time, I want to save time so I can finish the other rounds more relaxed and the line for the healing well is always short. Last tourney I used ulti once, this I'll use it twice. There's no shame in "paying" 60 or 90 gold for a nice dragon, if it were in the market as a special offer, I think anyone would take it
