yeah its fun to play but I wouldn't burn dust on White Eyes unless you have all the other must haves for sure. Hallazeal is a bit iffy too since we got that new Jinyu guy
(edit-- To elaborate, White Eyes is a deathrattle just begging for a polymorph/entomb/hex left & right. It's a miracle when he survives to actually give you the 5 10/10. Hallazeal is iffy cause soon Elemental destruction rotates and an aggro player nowadays are going face)
edt 2 - Another example. A few days ago on my Pirate Warrior I come across a Control Shaman. Granted I didnt see him play Jinyu but he wrecked my board. but even with just like 2 minions all I had to do was one shot White Eyes. Next he cast Ancestral on his Thing From Below. I one shot it with Axe,then one shot it again with Leeroy. Then next turn I swing at his face.
Now if he got a heal off I could have lost. But this shammy dies in like 6-7 turns and that's with 3 full taunts.
I repeat- Don't burn yer dust on White Eyes just yet.
you're realistically looking at mid shaman and maybe dragon priest? that's going to be able to reliably deal with your deathrattles in that manner, warlock can't do it, warrior can't do it, rogue can sap for tempo but it's not the same thing. With the way the games shape up today, white eyes goes off and if white eyes doesn't go off your other deathrattles will. one of poly's, one of entombs, and kazakus potions aren't going to be that effective.
there are lots of tools to shut it down in the card set, but they aren't really showing up in matches where they might otherwise be relevant.
In a perfect world you could play White Eyes>Ancestral Spirit for 2 5/5 taunts and 2 Storm Guardians in your deck (plus 2 more of each if somehow that matchup lasts until you play N'Zoth). In reality I think I have played this combo once without silence hitting White Eyes.
yeah don't make all in plays like that if they might be holding that sort of effect (unless you have to), put out the white eyes, if they kill it your white eyes did okay, if they poly it you didn't waste the spirit, if they don't do either you get to go off next turn.
