Cityscape Leveler

The eight-mana colorless slot usually buys a single big body and nothing else, but this one is a removal engine wearing a beater's clothes. The destroy trigger fires on cast and again on every attack, so it arrives as removal stapled to an 8/8 trampler that re-arms each combat: keep swinging and keep blowing up permanents. The catch is the compensation clause. Whatever you destroy hands its controller a tapped Powerstone token, refunding part of the value you just stripped. But a Powerstone is deliberately hobbled mana, useful only for artifact spells and abilities, so the opponent gets material back that they cannot convert into the cheap creature or spell they most want to redeploy. That built-in payback is the mechanism keeping a repeatable "destroy up to one target nonland permanent" from being flatly oppressive: you are always handing over something they have to work to convert into board presence. Unearth is the second act, but note its shape. Because unearth puts the card onto the battlefield rather than casting it, only the attack trigger comes back online; the cast trigger stays dormant, so the graveyard version is a one-swing, destroy-something-then-exile threat. Colorless removal that scales with combat is rare precisely because it sidesteps the color pie's usual price on destruction, and the Powerstone tax is what lets a construct with no color identity do a Mardu control deck's job.
