When I have 5 energy I fight and then wait until about 1 minute and 30 seconds left before my streak's up, then fight again, usually finishing the fight with less than 60 seconds left before my streak expires. This way I can get a 10 win streak.

Like an earlier anon said, if you wait 25 minutes during your first fight after spending your 1st energy, you will regenerate that first energy and have 5 when you finish. Then you immediately duel again because sitting for 9 minutes with 5 energy is pointless (since regeneration only kicks in when you have 0 to 4 energy). And then you just do what I said in my first paragraph, and you will make it to a 12 win streak instead of 10.

Now let's math it out; if you buy 5 arena energy for 5 gems, you'll be able to get 12 + 5 = a 17 win streak. However, if you employ the "wait 8:30 minutes" strategy, you'll regenerate another 2 energy during rounds 13-17, letting you get 19 wins, netting you the 15 and 18 streak rewards. That's 1 and 2 enchanted keys, 3 total, for 5 gems. Of course there's the risk of losing, but if you don't lose, I'd say paying 5 gems for 3 enchanted chests is a good trade.
