1/2 poisonous form counter early Giant in Evenlock
4/2 rush form guarantee 3 mana 4 dame reactive card (take down Hench-clan Thug in Odd Rogue)
1/6 taunt form good against Odd Paladin
1/4 dame spell dame is actually ok in some situation (good combo with Swipe)
At least it is good in current meta. Although each individual form is not strong (common eff) but the flexibility make them become 1 Legendary card.

I think this card is not bad. In mill druid, when our deck is empty, we can play this card + Innervate + Naturalize. Next turn, we draw and take 3+1 dame, shuffle 2 Corrupted Blood into deck, then play King Togwaggle and win because 2 Corrupted Blood will be infinite loop (?). 
The problem is the turn before we win, we really do nothing. Skulking geist is also a problem. However, pros of this combo is that we don't need twig or play Florist.
In conclusion, I think this card is good tech card ịn mill druid. Depend on what we dealing with, we can choose Azalina combo or this card combo.
