We kid of course: it's an MTG Arena bug , one seemingly introduced in the latest update
Whenever any creature dies, you gain one life and every opponent loses one be that your own creatures you feed to a Viscera Seer, or your opponents' that die for any reason
Deflecting Swat needs little introduction to many Commander players, and Untimely Malfunction doubles as a two-mana target-switching effect that occasionally blows up a threatening artifact
Its a fine rate for the effect, but the addition of flashback makes this almost the reanimation equivalent to cards like Timeless Witness you can reanimate two things, or gain value from discarding or milling it
They read, Whenever an opponent sacrifices a nontoken permanent or discards a permanent card, you may put that card from a graveyard onto the battlefield under your control. That means you can attack in multiple ways, and as long as youre interfering with your opponents hand and board state, youll benefit massively from it
How that translates to a competitive, collectible strategy game remains to be seen
