A 4/3 with reach and trample is an honest blocker that swings back for real damage, but the design work lives in the graveyard clause, where domain does something subtler than the usual "count your lands for extra combat damage" application. Here the mechanic scales a recursion cost. The ability starts at , and every basic land type spread across your manabase trims a generic off the price, bottoming out at when all five are represented. The spider returns tapped, and the exile rider is the leash. Once it comes back, it picks up a replacement effect that removes it from the game on any future departure, so this is a single loop rather than a perpetual one: you get the body back once, and the next time it leaves, it is gone for good. That clause stops a discounted recursion effect from spiraling; no sacrifice engine can churn the same creature turn after turn, so the return has to justify its mana honestly. What makes the return cheap is the same wide land spread you were already assembling to fuel your other domain payoffs, folding graveyard resilience into math you were paying for anyway. The reward is contingent on that count, which gives green a recursive threat that rewards a deliberately broad manabase rather than one any two-Forest deck can slot in.
