4. Ragnaros, Lightlord
The only downside to Ragnaros, Lightlord is that he fights with Tirion for the eight mana slot in Paladin. This card is insane. An 8/8 for eight that also heals you massively the first turn it is in play? Oh, and it continues healing every other turn it lives as well? This may be the most game-swinging card I’ve seen printed, allowing for absolutely massive turnarounds as you not only stall your opponent’s push, you also provide an 8/8 that they must deal with or accept that you will have infinite life. Obviously this card doesn’t fit in aggressive Paladin lists, but every Midrange and Control list in the future will be insane not to run Ragnaros, he is one of the strongest legendaries thus far. He only places under Fandral and the others because he is a Paladin only card that only fits in a few archetypes at the moment.
