IF this question (and from the way it is worded I assume it is) from the perspective of a player that is STILL below level 50, then (as the previous poster said), it does depend on the card, some cards may be obtained from Raid Blitz and Carnage keys, and there is the Premium, and mega rare Keys, not counting if you are using real money you can make purchases from the purchase card packs. With the recent change to the Premium Key and Free and Special Free card pack, that's no longer that difficult to achieve.

IF you are refering to how it was done before the prevalence of the Raid keys, there is a very simply method, and yes it does require use of the bazaar.

any card you have previously owned on the account may be requested, regardless of the level of the card, you cannot however purchase that same card from the bazaar even if you meet the just mentioned past ownership parameter. That is to say, for example, you are level 15, and just received that free Belili that was given to all registered GREE accounts earlier today, even though Belili is an Ultra Rare card that would require you to be level 60 to PURCHASE it from the bazaar, you could put up a common or uncommon card on the bazaar and request a Belili in return. Now that trade will never go through except by people with alts transfering cards around, no REAL players will accept such a trade other than maybe guild members passing no longer wanted cards to newer players in their guilds.
