Spiked Ripsaw

A static +3/+3 that reattaches is only the frame; the real design lever is the trample rider, which converts a Forest into evasion one attack at a time. That sacrifice is not a drawback bolted onto an otherwise generic stat-stick: it is the honest tax that keeps a repeatable "push damage through a chump wall" effect from being free. The more you lean on it, the faster your own land count contracts, so the card wants a green aggro shell built to flood the board and cash in surplus lands as damage, not a deck that needs every Forest for mana. The Equipment chassis compounds this: unlike an aura, the buff survives the death of whatever holds it and re-attaches at sorcery speed to the next attacker, letting the +3/+3 persist across a grind while trample stays a per-turn resource paid for individually. The catch the honest evaluation has to include is the cost curve: this is not a cheap enchantment stapling +3/+3 to a creature in one shot. Getting the buff onto a body takes casting the Equipment and then paying the equip cost, a two-step investment before any land ever hits the graveyard for trample. Read that way, it is a plain-spoken aggressive tool with a built-in evasion valve that runs on the one resource green tends to have in surplus, but it charges you up front for the privilege.
