Even a relatively tame set of instants or sorceries like Pongify, Serum Visions, and Faithless Looting can completely lock down a game while searching your deck for whatever card you need
If were allowed to get out of hand, theres also the opportunity to get the Springheart Nantuko on any of these (oh, if its the Baloths!) to make token copies of them with every land, turning a modest 5-land entry on a turn from 5 4/4 beasts to 5 copies of Frenzied Baloths, plus 1 + 2 + 3 + 4 + 5 beasts, for a total of 15 4/4 beasts suddenly appearing on the field
Hazel's Brewmaster reminds me of Deathbonnet Sprout / Deathbonnet Hulks back side, though its an attack trigger that makes Food tokens instead of an upkeep trigger
While many demons encourage you to use life as a resource, having to also pay mana in order to get the tokens and only on your own end step makes him feel a lot less powerful than he otherwise could have been
Exploration plus Crucible of Worlds plus a landfall trigger that fills the graveyard doesnt feel like something that should have been printed on an individual card
