Pumping on Mishras Bauble and not just instants and sorceries is a big deal, too, and plotting will also come up in Modern some of the time just to tax your opponents mana more when you expect that they have a Fatal Push or Lightning Bolt at the ready
I like this one in decks like Borborygmos Enraged, or Teval from Tarkir: Dragonstorm Commander

You could find cards like Feed the Clan or Jaddi Offshoot for dedicated lifegain, but if you wanted lifelink or even just a few points of life tacked on to an otherwise competitive card, you had to play something like Siege Rhino, Seeker of the Way, Soulfire Grand Master, or Sorin, Solemn Visitor
Jund is fantastically versatile for filling the rest of the main story beats and factions in Middle-earth, and rounds things out nicely
