Gerrard's Hourglass Pendant

Two effects share this cheap artifact, and they have almost nothing to do with each other, which is exactly the point. The first is a static hate piece: any player about to take an extra turn skips it instead. That is a one-mana, flash-speed off switch for the entire extra-turns axis, a category of effect that has usually cost more or arrived stapled to a body. Because it hits every player and never expires, it functions as a persistent tax on Time Warp chains and time-loop combos alike, and the flash means you can leave mana up and land it while the extra-turn spell is still on the stack, denying the turn before it ever resolves. The second effect is a mass reanimation button gated hard: it returns only the artifact, creature, enchantment, and land cards that hit your graveyard from the battlefield this turn (no planeswalkers, no battles, no slow-filled yard), so it rewards a board wipe you caused or a mass sacrifice you triggered. Exiling itself as part of the cost means you get one shot, and the returned permanents arrive tapped, so it rebuilds rather than loops. The design tension is that the two halves pull toward different tables: the static tax wants a patient control shell, the recursion wants a self-destructive board. Bundling both onto one legendary artifact bets that the same deck often wants to punish greedy turns and to recover from its own carnage.
