Lagrella, the Magpie

Most exile-on-entry designs freeze a single threat and hold it hostage; the load-bearing wrinkle here is "controlled by different players," a targeting restriction that scales with the table. In a duel it exiles up to two creatures, one of yours and one of an opponent's, but the clause only stretches toward its full reach when three or more players are parked around the board. The exile is a rented answer, not a permanent one: everything returns to its owner the moment the 2/3 body leaves, so killing Lagrella hands every parked creature back at once, and the whole board knows it. That fragility is the design, not a flaw in it. The +1/+1 counters are the piece most readers misread: the trigger fires when an exiled card enters under your control, and the natural target for that clause is a creature of your own that you tucked into the removal package alongside the opponents' threats. Bundle one of your own creatures into the pile and, when Lagrella dies and everything returns, your creature comes back two counters larger while the opponents' threats simply go home. The play, then, is to weaponize Lagrella's own mortality: stash a table's worth of blockers as leverage, treat them as a countdown rather than a cage, and arrange the return so it grows your side of the board instead of just resetting it. Thin in a duel, alive as a diplomacy-and-tempo piece in a crowd.
