With enough time and Zombie creatures, Endless Ranks of the Dead will create an impressive army of 2/2 black Zombie creature tokens so long as board wipes don't reset the board

(I should also mention that this doesn't include reprints, so fetch lands are counted as Zendikar cards, not Modern Horizons 2 cards, so they aren't skewing the data.) While Modern Horizons sets add a lot of interesting new cards to the Modern format, at this point, it's clear that they also add a lot of expensive cards into the Modern format, which in turn ends up increasing the cost of playing the format
Because you are so streamlined you only have one or two bounce spells, one or two counters, perhaps only a bit of burn going face etc
Item, location, and action cards can all be used without having to wait a turn
