Overgrown Battlement is a real workhorse for defender decks, taps for absurd amounts of mana once you've got your walls in place, and can produce infinite combos with the right combination of untap effects
I think this is a super fun and exciting bomb that can completely blow up a game, but its 8-mana cost dictates that itll only ever really see play in casual Commander pods
What a lovely experience
Marcy: This is a card that doesnt have a place in Standard, at least not currently, and certainly seems far more for use in a Commander token deck, one that uses Jinnie Fay and Jetmir, or similar token explosiveness
I've also been trying to find a first edition Japanese base set card to look at, but for some reason an image of one is tough to locate
Theres Tron and maybe other ways to ramp better to big Eldrazi, but that seems decent and its colorless
