yugioh black luster soldier envoy of the beginning deck Yu-Gi-Oh! - Invasion Chaos - 25th Anniversary Reprint From the Yugis Legendary Decks set Yu-Gi-Oh! Black Luster Soldier Envoy

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

If it would be destroyed, destroy this card instead

This is one of the more tame cards, but a colony of rats is nothing to joke about

Oonas Grace had to cost three mana because a two mana version would grant every land Cycling, but one can imagine an Escape cantrip that costs one mana, but whose Escape costs an exorbitant six cards or four mana (but not both)

On second thought, dont do that

60 HP and a first attack with a base of 10 (before some additions) is not befitting of Nintendos genetically engineered monstrosity
