Secluded Courtyard

Cavern of Souls solved a real problem for tribal decks (an uncounterable creature spell in exchange for a colorless-only mode when you want off-type mana), and this is the budget-conscious dilution of that idea, trading the counter-proofing for a cleaner mana profile. What you lose is the "can't be countered" clause; what you keep is the part tribal decks actually leaned on most nights, which is fixing that pays for a whole board of one creature type without straining a color-hungry manabase. The chosen-type restriction is the pivot: the any-color mode is locked to creature spells of that type or activated abilities of a source of that type, making the land a commitment device rather than a rainbow land in disguise. Declare Goblin, and it fixes for a Goblin deck and does nothing generous for the splashed removal spell in hand. That constraint is what earns it the untapped, no-life-cost entry that older fixing charged for. It also quietly does double duty by feeding activated abilities, so a tribe built around tap-effects or pump costs gets its engine mana, not just its casting mana. A design for the deck that already knows what it is: single-tribe, color-hungry, and unwilling to run its curve off basics alone.
