mtg cards like craterhoof behemoth #138 Holo from Tarkir: Dragonstorm (TDM) Proxy where X is the number of creatures you control. Craterhoof Behemoth (Retro) (480) -

(4/17/2020) If the power of the target creature cards change while in your graveyard, most likely because one has a characteristic-defining ability that defines a * in its power, the total power of the creatures may become greater than 10

There would be a more sustainable model for this (which was a huge positive for the game and for the environment!), but there would also be a price: certain amenities would have to go, which meant no more oversized commanders

And to me, that felt like we were sword fighting

At the beginning of your upkeep, if there are 100 or more tower counters on this enchantment, you win the game

I also like this in Azorius Flyers with evasive aggro beaters like Judge's Familiar that you can now win with in one hit unlike the beefier Green stuff which is a faster kill

Of course, in hydra tribal, even better, but also if you have a deck with clones, clones of the back of Polukranos here will see each other die to trigger multiple times for a geometric amount of hydras
