mothman mtg card The Wise Mothman where X is the number of nonland cards milled this way. NM Foil The Wise Mothman,

In fact the printing of Unholy Heat (and to an extent Solitude) has mostly pushed out cards like Tarmogoyf out of the format, as the removal in the format is now so efficient that creatures either need to be one-mana, so you trade at an even level (Dragons Rage Channeler and Ragavan, Nimble Pilferer), too large to be killed by Unholy Heat (Deaths Shadow and Murktide Regent) or generate immediate value upon being played (Solitude, Fury and Omnath, Locus of Creation)

To add a little context, I have a sea monster deck that runs 37 lands with an Average Mana Value of 4.81

Paradise Druid and Sylvan Caryatid are slightly more resilient to removal

Forgotten Ancient is one of it's best friends with a trigger at the upkeep to almost guarantee you get to the main phase with exactly the number of counters you want
