There are times, when they don’t pull it off correctly and don’t have the right combo, there is still the potential at times to finish them first, however, when they have the all the combo card its not possible, and that’s when they start copying the parrots to repeat the spell over and over and that’s when I will concede, because like you said, it is a waste of time sitting there till the end, when you know what the outcome is going to be.
The duke does not make sense to put in some decks, especially not in aggro decks, not in Legend. I have not seen a single person play this card in legend in the last 2 weeks. It might be in some control decks like Highlander DK, or other Highlander decks, but like I said, it make no sense to add in my decks as I mainly go up against aggro decks with a few exceptions, so its to slow of a card to run.
For any of you wild players that also play Standard, you will remember the wonderful Turtle mage deck which essentially did the exact same thing, except instead using time warp for you to miss your turn, they just keep playing copies of Tortollan Pilgrim that would repeatedly cast Blizzard, freezing your board preventing you from attacking with your minions and than doing dmg with sunweaver warmage each turn. They nerfed it in standard, yet they allow in WIld, it makes no sense. (allow it with time warp)
While I get they want to put all their love and attention into Standard, they also need to pay attention to wild.
Its starting to come to a point where they need to start addressing the unbalances in wild. However, what they have started to do rather than balance to address some cards, they have started to ban cards outright. We saw the first Ban with the warlocks SOS deck with the quest, and they have added a few more cards to the ban list since. I get that they don’t want to nerf a card that will have an understeered impact in Standard, however, these cards are going to eventually rotate into wild and you can’t keep them banned forever.
