I think silence will be a big thing in new meta. If this minion is silenced its a huge tempo loss. Too much of a risk to play this one.

Regular doomsayer could be silenced too but he is only 2 mana cost not 5. And he can kill everything, threatens your opponent much harder.

And there’s a lot of stuff that can be played for 5 mana to kill a harmless body with 7 life for free. So it’s definately not a control deck card, because by the turn 5 you need something reactive to compete vs aggro decks.

Should be buffed to: “Whenever this minion takes damage, summon a 3/3 grim patron… with taunt and charge.”

Actually I think you can use it with Flamewaker pretty damn good because its a 1st mage’s 0 mana spell.
So you can for example target your Flamewaker for 0 dmg for 0 mana to make him deal 2 additional points of damage.
