While Child of Alara is still a powerful commander, this 6/6 for WUBRG (One White, Blue, Black, Red, and Green mana) and its ability to destroy all nonland permanents upon death, isnt all that exciting
You lose protection and a win condition, but the trade for that is a commander that taps for obscene amounts of mana
We can play Phyrexian Unlife if we want, plus Cartel Aristocrat as an additional sacrifice outlet
The only other upside I might see is with proliferate, but even with that strategy, the mana value seems too expensive and curve-unfriendly
There are plenty of plays that can get you in a winning situation with just a few specific Dragons like: Goldspan Dragon Ancient Copper Dragon Hellkit Charger With Goldspan Dragon and an Ancient Copper Dragon out, you can generate tons of Treasure tokens and then make bonus mana off of them
