It's a good point, I'll add that note to the guide.

Honestly really happy to see someone's still playing the deck - and with Sideshow Spelleater, I have also removed it from my current list, and replaced with Kabal Trafficker to experiment with the card - but Eater of Secrets is a very reasonable substitution.

Anyfin' is definitely a difficult matchup. When I have won against them, it's by forcing the first two equalities on large boardstates, while never actually playing either Sludge Belcher or Defender of Argus. Then you taunt up before their last anyfin. I've also beaten the deck by dropping a Mal'Ganis with Voidcaller and taunting up two Dreadsteeds. So if you want to improve the matchup, I would suggest adding Sunfury Protector.

Not my deck, but I've ran similar.This deck is a really late game winner, with the exception of rush decks that get a crazy start, you will reach a point after you stabilize where you don't want to draw cards. But given the control nature of the deck you won't always be playing 10 mana every turn. So any hero is prefered. But the main reason to run Sideshow over Sir Finley is that Sideshow is the only way you will beat Fatigue Warrior. Wait for them to play Justicar and boom 4 armor every turn.

Exactly as FinelyPrinted said, in the early and mid-game life tap is integral to draw into the control spells and dreadsteed combo pieces, but after a certain point you no longer want the warlock hero power, and literally any other is better - and sideshow rather than Finley means I can copy an upgraded one like Tank Up.

its worth noting though that against control warrior it's quite common to just overwrite the armour and tank up hero power with jaraxxus as soon as the opponent has played Grommash - if you're gaining lots of armour they'll realise they can't burst you down with grom and will play him as removal, then you're very safe to jaraxxus, which is really strong even if you're losing 15 life and like 10 armour in the process.

Wouldn't Jaraxxus be your way of beating Fatigue Warrior?

Jaraxxus can be a way to beat fatigue warrior, yes, but just as I said in my other reply, burst potential from Grommash Hellscream makes it so that jaraxxus can be quite dangerous to play. Sideshow spelleater either gives you an alternate way to best them that doesn't put you in burst range, or it convinces them to use Grommash as removal so you can then play jaraxxus with impunity.
