Theres just too much removal/too many board wipes in my metagame! If creatures are rarely surviving, and you cant keep a board together, consider Revel in Riches
(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
Having unlimited access to repeated cheap life gain can turn on dozens of powerful payoff cards
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
A cheap card like Sleep Magic is a good way to stall powerful opposing creatures, or you can eliminate them with something like Overkill
