I would not craft anything from the Ungoro, Frozen Throne and Kobold expansion unless you are truly interested and vested to play the deck to feel good, for e.g. Kingsbane for Kingsbane Rogue. (Or you have a certain unexplained love towards the card for lore or attachment reasons because you played Warcraft.) I did that previous cycle and regretted spending the dust for only 4 months of playtime. Crafting something from this cycle (Witchwood, Boomsday, Rumble) and the card could still be there for a year and 4 months. Imagine if you crafted Kingsbane a year ago, you still have a year and 4 months to play the card and you wouldn't have this dilemma now because you already have the card.

While it is impossible for Kingsbane rogue, there are plenty of replacement for the missing cards for an Even Paladin deck. You can sub in more tech options like Black Knight, Mojomaster Zihi, experimenting with Spirit of the Tiger, or second copies of Argent Commander, Avenging Wrath, Windfury Harpy etc. Or take your paladin collection in a different direction and play a Healadain or Control Paladin instead.
