The card at your link went from a packout facility worker to Rusty at TCA
Pairing that with Speed Lightning Energy (Rebel Clash) to have a better draw engine and Flaaffy (Evolving Skies) to accelerate Energy makes this a competitively sound concept
But in multiplayer your options and outcomes are no longer so reductive or cutthroat
Krav, the Unredeemed // Regna, the Redeemer Krav, the Unredeemed and Regna, the Redeemer are an excellent commander pairing for an Orzhov deck that is fairly open-ended on how you build them, since they support Lifegain, Sacrifice, +1/+1 Counters, and even Tokens
This ability alone could end games instantly, especially late-game when decks were already thinned
Since LV.X cards can use attacks from the Pokmon underneath, dont rely only on Final Blowup
