Cyclopean Snare

The whole pitch is a tapper you never permanently lose. Most repeatable creature-tapping comes attached to a body that can die, so a sweeper takes your engine with it; this one returns itself to hand the moment it fires, which means a wrath finds nothing to hit. The resilience is expensive: five mana per cycle ( to activate plus to recast it from hand), paid every single time, which makes it a slow way to neutralize one attacker per turn rather than a lock piece. There is a real window for opponents, though, and it sits exactly where the self-bounce does not protect it. While the artifact waits untapped on the battlefield, instant-speed artifact removal answers it cleanly; and even after activation, the bounce comes after the colon, so the thing is still on the battlefield with its ability on the stack, vulnerable to a destroy effect in response. The self-return only saves it from sweepers and from removal cast on an empty window, not from anyone holding up the right answer at the right time. The card rations a tap effect across multiple turns and multiple chunks of mana: a grinding control tool that survives the board getting wiped and slowly wins an attrition war by keeping one creature off the table indefinitely.
