Alas, the Vanguard format never really gained much traction, thus the prices of the cards are stunted greatly by the lack of demand
Kardur only has 930 decks to its name on EDHREC, but its truly a force to be reckoned with
Dragonlord Kolaghan really suffers from not blasting opponents when they cast duplicate instants or sorceries and both fail the dies to Heros Downfall test and cost a lot of mana
For +1/+1 counter payoffs we have stuff like Hopeful Initiate for repeat disenchants and Elite Scaleguard to tap down opposing blockers but we also have a cheeky combo with Scurry Oak / Herd Baloth + Rosie Cotton of South Lane / Ivy Lane Denizen for infinite creatures
Card games that have been printing for 30 years still have errors, misspellings, and hiccups like clockwork every set
