I really don't understand how Rag is winning. It's a good card, sure, but the effect is so utterly boring and bland in general. There are non-legendary minions with very similar effects. Reno had a very unique effect for his time though, and created a huge number of archetypes.
Thinking of it... I start to see how Rag could actually deserve a win.
Sure, is a boring card by himself that does'nt see play beyond classic, except maybe some big priest thingy, and of course battlegrounds and mercenaries... but he also as the first one big random card in hearthstone's existence. Back on the days, there was barely any randomness, few weird shenanigans (because Millhouse and Cho were'nt any popular). Mad Bomber was no meta. There were only four founding fathers to Hearthstone randomness: Sylvanas, Knife Juggler, Thoughtsteal, and Rag. Of all these, Rag was clearly the most radical, since priest was not a good class at the time, and Ragnaros was far better at pulling unexpected wins and frustrating fails than Knife Juggler and Sylvanas. Back on classic stone ages, Rag was the original Yogg Saron.
I still wanted Reno to win tho, he is awesome in every way, and also gave us the craziest plots this game has seen in a long way. However, there is no shame on voting the original random meme card over our Lord and Savior. In the end, it's just a minor rumble between gods crazy beyond our understanding on that word's meaning.
