Elite Spellbinder 3/1 flying is already a fast clock, but the most annoying part of dealing with Elite Spellbinder is that it makes you pay more on a given card, so its a nice disruptive element for aggro decks
Skullbriar, the Walking Grave I like to think of Skullbriar, the Walking Grave as the progenitor of Arenas perpetual mechanic, where buffs to a creature persist across different zones
and Winota, Joiner of Forces, among a long list
Stuff like Snuff Out or Dismember are already heavily played cards, but here, you get to draw a card from them because you lost 4 life, and you also get to drain your opponents for 2 life, offsetting your life loss
Changing pace a bit, you have Elsha, Threefold Master to go more in the token approach
Town Greeter fills a similar role in Golgari Roots and Golgari Graveyard, stocking the graveyard while generating card advantage
