Is 600k Power achievable in 10 days?

If you get lucky with event drops, you can reach 400k power pretty quickly. Save up lots of gems, gold, and summon tickets. After buying 30 Grand Tournament Gloves from Arena 7 and 990 gems, then buying 500 runes per 5000 teeth, upgrades might take 50/100 quickly or 100/150+ if slower. Lower tier decks will likely need more. The roulette disco bonus is tempting me to pay.
