 I bet the last one before the reveal stream is definitely going to be Paladin legendary

The next one is more like a druid rare

It's a druid rare minion with rush I bet

the last two are paladin cards

The bewitched guardian seems a bit strange, i'm 90% sure it is a paladin card (epic), but it has also some nature-like details (leaves and bark) that could hint toward a druid minion (rare?).

Paragon of light is the 2nd paladin legendary almost surely 

Bewitched Scythe is a druid rare

Paragon of Light is a paladin epic

Bewitched guardian - epic - neutral

Paragon of Light - rare - priest

Bewitched guardian: Paladin - Epic

Paragon of Light: Paladin Secret - Rare

Bewitched guardian - Druid rare

Bewitched guardian - Paladin epic 

Paragon of light - Paladin rare

Paladin Epic!

Bewitched Guardian: Druid rare minion with taunt and costs more than 5 mana.

Paragon of light: Paladin epic spell that gives a buff, maybe divine shield + something else.

Rare Paladin Secret

Paragon of Light: When a minion is attacked give it Divine Shield

Paragon of light epic paladin

Seems like the Paladin legendary has been already leaked :/

So nobody is bothering to guess the effect anymore?

Paragon of Light looks almost certainly like a Paladin card, sounds like it should be a minion. If Paladin doesn't get a card with lifesteal this expansion then I would be very surprised as both The Glass Knight and the previous expansions heal dependent cards suddenly take a huge hit before ever having a chance to become a thing, given the rotation of Wickerflame. I would also be surprised if it didn't have lifesteal as a keyword rather than something like, battlecry: give another minion lifesteal, because Countess Ashmore then has barely any playable lifesteal cards to draw in almost any class. Paladin is also then left with basically no reason to ever play rush which is one of the major themes of this expansion.

So I'm going to guess:

Paragon of Light - Epic - Minion

6 mana 5/6

Lifesteal

Rush

We will definitely see another Paladin secret this expansion and I think it will be a strong one but this is unlikely to be it.

I agree that it has to do with paladin healing. But I think it's gonna be an expensive buff spell, like Spikeridged Steed.
A spell that makes the targeted minion The Paragon of Light. I don't know much lore so I'm not sure if that title means something. But I would guess It would turn the minion in a support tool, giving it something like: "Give a minion Divine Shield and 'whenever this attacks restore +3 health to all friendly characters'" or something like that.

paladin legendary idk what paragon of light is because I'm not a warfraft weeb

For the final reveals, I'm calling a 1-mana 0/1 'Tree Frog' Hunter Beast with "Whenever you summon a minion, restore 2 Health to your hero"
