Honestly, I dont see the difference between the two, Sure the new ones only have 75 and the old ones have 100. THe new ones have a blue sepereator and the old ones seperator is gold. But honestly I like em both equally. I dont see much of a difference.
TnT Ran Mana Drains??? I played GOOD TnT, Ya know the kind that doesnt run cards like Mana Drain. Artifacts and Mana Drains just dont belong together. Maybe in the new sets they might make more aggro-like artifacts(how ever they managae that one) they might work, but I doubt they will ever go togethor.
It seems like normal oath, witch is a decent deck. I suggest Oath Salvagers, you can get the decklist almost anywhere. Dan Emmons won the beanie exchange playing it, and whooped my butt pretty good, I was playing typical Dragon. Congrats to Dan and good luck building ur deck.
