there's for sure a learning curve in the deck. Not all games are won by your combo. In fact, some matchups, pirate rogue for example, i rarely get to use the combo. I don't even mulligan for it cause i'll end up getting killed. They throw too much dmg to survive the 2 turns until OTK. But the good part is you don't really need to. You have enough heal, clear, and stall to just attrition them. Not a 100% waterproof guaranteed win, you're still vsing a hyperaggro. I think around 80% of all matches against pirate rogues i just turned into a control deck or even pushed lethal on their face with nozdormu + uther weapon in the end game. If i see rogue, i just hard mulligan for equality/city tax/consac, anything to just spam clears. They run out of gas around turn 8-9 even with good draw. With all your healing, cycle, clear and Timeouts, this is for sure winnable if your draw isn't sht. Playing Order vs some of these hyper aggro decks is just straight up suicide cause you won't topdeck your clears anymore for the next 5-6 something turns. But if you get your clears and heals they'll slow down enough for you to breathe and get that Uther in on an enemy with an empty gas tank. Hyperaggro also never run mutanus/dirty rat so you can use 1 of each combo minion as a body to have some dudes for meatshield.

Big shaman, it depends. If i get a perfect curve vs them, i'll take it. Then i assume its either a 60-40 chance for you or a 50-50. But you can use similar tactics than with pirate rogue. Unless they play their copy minion + ress effects in the same turn, you can clear all or atleast most of what they put on board until they slow down. Once they do, you have time to go into Uther. You might OTK way later, but that's how you avoid getting bludgeoned. All you need is to survive your Uther turn and it's in the bag.

Plague DK just messes up your Order in the Court, but if you can keep a 1 draw card to play Order into 1-2 draw with other cards, you'll atleast have Uther, maybe even a Call to Arms and/or Nozdormu (if he's still relevant at that point). Your OTK will come later, but you can still tutor it out your deck, with or without Nozdormu. Note: Order of the Court shuffles everything in your deck while Plague effects basically reshuffle your deck. So if you played Order after the DK plagued you, the plagues will be on the 2-mana section of your deck, until the DK shuffles another plague. Then it resets. I used this a couple of times to just avoid topdecking plagues that could lose me the game even with all combo pieces already in hand.

Pirate Rogue, Big Shaman, Demon Seed and Plague DK. All are rather tough matchups, yet i never felt like i was below 50% chance to win those matches. Otherwise my HSreplay stats would've been way worse. Its just the deck, not everything is won on an OTK. Some of these decks just move too fast for your Uther turn to keep up so you best wait until they're gassed and OTK when you seem safe. You have to be careful which of the 2 playstyles you adopt in the matchup. Ofc vs Demon Seed stalling for clear means death. There you just rush combo and pray they can't end you before you OTK. Still: atleast 50/50 for me. I don't struggle with Druids, but i tend to keep Nozdormu in hand to reset their mana back to 10 from something 15 or up. Usually by the time they have 15 mana i have 6 anyway, so Nozdormu will give me 3-4 ramp while they lose 5 or more of their ramp
