The Dragon Ruler archetype is incredibly efficient at filling the GY with material to use on follow-up turns, which allows players to win games if they last several turns, because they will rarely run out of resources
It also gives you a full deck while you build into a more powerful version, whether its this one or your own
Theres also The Book of Vile Darkness, which fuses together with Eye of Vecna and Hand of Vecna to create Vecna, an 8/8 Zombie God that lets you draw cards, create zombie tokens and just generally be bigger than everything else
With each and every expansion, new cards are introduced, spawning new archetypes or redefining existing ones but not all sets are created equal
Storm This is not a deck I have successfully drafted myself, but its one that I have seen be very effective
Coupled with Runic Armasaur, you have a mini taste of Stax, however, you may find a target painted on your back thanks to this
