In EDH, Id play it over Generous Gift in most cases where the double pips dont scare me off
Bojuka Bog is really the only land that comes into play tapped that sees competitive play, but thats because its the ETB effect thats more important not the mana it produces
Mathas, Fiend Seeker is a Mardu Vampire commander that uses political bargaining to manipulate opponents' removal choices and gain advantage
Also, Ive left out anything that lets you play those cards without playing their manacost or lets you play from your opponents library
Your lands activated abilities all cost one less to activate, and then any land creatures you control get +1/+1
Checking out what content creators in the community are doing with the latest decks, like The Command Zone on YouTube and aggregation sites like EDHREC, will provide an overwhelming number of cards to consider swapping in
