Nethersoul Buster Card Review
It reminds me a bit of the Darkshire Councilman back from Whispers of the Old Gods, but instead of gaining the attack slowly, it gets everything immediately. All or nothing. That’s why it’s not really a 3-drop – if you play it on Turn 3, you will just play a vanilla 1/5, and that’s terrible in Zoo (or in any other deck, to be fair). In order to make him work, you need to play him with another card. Luckily for Warlock, the cards that synergize with him cost 1 mana – Kobold Librarian, Flame Imp and the new Crystallizer. To be honest, the card is good enough even with just Librarian – you get a 3 mana 3/5, which is fine. Then, in case of Flame Imp, the stats jump up to 4/5, and with Crystallizer – 6/5. The last one is especially powerful, as a 6/5 minion can wreck havoc on the opponent in an aggressive deck like that.
Does it mean that it’s useless if you can’t combo it? Well, not exactly – you can still play it on Turn 5 with Life Tap. It will make it a 3/5, so the play will be a bit slow, but it’s by no means a dead card in the mid/late game even if you can’t combo it. I feel like Zoo puts more and more focus on self-damage, and that’s a really interesting approach to the deck – if they release a few more synergies, it will definitely be THE way to play it. As for right now, it already starts to look promising.
The main issue was the same that Duskbat had – if you have a 3-drop, you usually want to play it on Turn 3, not wait an extra turn or two to pump up his effect. But it might be worth in this case. Duskbat, while it was really good if it triggered the effect, could never reach the crazy good levels of this card. Crystallizer alone is insane with this, and if you can let’s say Crystallizer + Flame Imp + this one in the mid game, your opponent absolutely needs to clear it right away or he takes 9 damage. So I wouldn’t overhype the card, but it looks pretty decent.
Card rating: 7/10
