If I had to venture a guess, Id say most decks should run no more than 20 but thats a ballpark figure
I think the Inversion is a slightly stronger aggressive card in a deck with sufficiently meaty dorks that they can survive a -3 toughness hit
Instead I usually opt for a Mob Rule, which can steal most of the things you need to try and win/eliminate a player for only six mana
Right before his Conclusion, Frank talks about how for the last three Pro Tours (at the time in 2017), all the decks that won ran more lands than the average
This could lead to creative and fun gameplay
